A mattress with a 5.0 foam density doesn’t say much about the love seat you’re considering, for instance. It is produced from solid beads of polystyrene. –31-37; Tensile strength, p.s.i. Newsletter. Its uniform, closed cellular structure limits radiant, convective and conductive heat transfer. EPS R-value per inch varies with density because the higher the density, the smaller the open void air spaces between beads, which results in a slightly higher R-value. EPS board produced to meet the requirement of Type I EPS has been tested and found to fall within 10 to 14 psi. Home » Forum » General Discussion. Surf specific EPS. – 58-61; Thermal resistance, R/in. Once in the mold, the pre puff beads are again steamed to form a block that is anywhere from 37-1/2″ – 54″ x 49″ x 121-1/2″ – 220″. EPS is a rigid, closed cell, thermoplastic foam material. A common misunderstanding is that the density of foam – in a mattress or pillow for example – determines its firmness. Density tells you the weight of the foam more accurately than the firmness. However, one of the most confusing things about foam is the relationship between these characteristics. http://www.EPSFoamPro.comBasically HD foam stands for High Density Foam. 0000031203 00000 n 0000025594 00000 n Select Your Blanks from Catalogs Below. XPS is another form of a foam which offers improved surface roughness and higher stiffness with reduced thermal conductivity. By doing this we get a foam sheet that is flat, has a better surface finish, and a more uniform thickness than is typically available from insulation suppliers. 0000009281 00000 n This qualtiy product is less expensive than alternative forms of rigid insulation, giving you the best value in the industry. Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3.

Density affects foam durability and support. 4 Environmental Product Declaration EUMEPS – Expanded Polystyrene (EPS) Foam Insulation (density 15 kg/m³) show that “no deficiencies are to be expected from EPS fills placed in the ground over a normal life cycle of 100 years.”/Langzeitverhalten 2004/, /Long-term … Recycled Content – EPS foam may be molded from virgin beads, or a combination of virgin bead and recycled material content. x 24 in. What is Pacific Foam? The EPS foam is delivered by truckload and provided based on the client’s provided takeoff and specifications. The data on fatigue properties of PU foams are generally lacking. The data are largely dependent on foam producer, as used substrates and production technology decide on intrinsic structure and foam density, and in such a manner - on capacity to carry mechanical loads. It causes superficial yellowing and friability, but does not otherwise affect physical properties. 72 sq. 4 Environmental Product Declaration EUMEPS – Expanded Polystyrene (EPS) Foam Insulation (density 30 kg/m³) show that “no deficiencies are to be expected from EPS fills placed in the ground over a normal life cycle of 100 years.”/Langzeitverhalten 2004/, /Long-term … This isn't the case. Generally, neither water nor vapor affects the mechanical properties of EPS. 0000003722 00000 n However, EPS may absorb moisture when it is completely immersed due to its fine interstitial channels within the bead-like structure. x 48 in. 50% r.h. is 4x1013 ohm-cm. When choosing EPS, original equipment manufacturers realize cost savings across the board. Densities can range from 10 grams per litre (0.6 pounds per cubic foot) to 48 grams per litre (3.0 pounds per cubic foot). Block… Download Comparison Chart as PDF.

EPS is hand- and machine-shapeable, although because of the larger cell size, it’s not quite as easy to shape as polyurethane foam. Dry EPS R-value ranges from 3.1 to 4.3 R per inch depending on density. 0000001737 00000 n As seen in the table below, most properties of foams are strong functions of density, which allows a processor to fine-tune the exact performance needed by a simple processing change, without redesign of tooling. These properties, in combination with satisfactory engineering considerations provide the design flexibility required to create truly cost-effective protective packaging.With the average package handled by up to nine different people and with more than 445,000 packages a day per distribution facility, the risks of the distribution environment can be great. This pertains to all varieties of foam, including expanded polystyrene , polyethylene, polyurethane foam, and others. The thermal conductivity (k factor) of molded polystyrene varies with density and exposure to temperature, as shown in the table below. Many kinds of polyethylene are known, with most having the chemical formula (C₂H₄)nH₂. 0000005696 00000 n PE is odorless, tasteless, and generally harmless. `s8�'���q�Y��s�m7�[�N�_��7@5�Ʀa ����i`�����`惭eL��2@,�Þ���>�#� ��,37�d�]X�=E��C�;&�����ݹ�몂��b��� } zw6T endstream endobj 51 0 obj 184 endobj 22 0 obj << /Type /Page /Parent 19 0 R /Resources 23 0 R /Contents 31 0 R /MediaBox [ 0 0 612 792 ] /CropBox [ 0 0 612 792 ] /Rotate 0 >> endobj 23 0 obj << /ProcSet [ /PDF /Text /ImageC ] /Font << /F5 24 0 R /F6 29 0 R /F7 25 0 R /F8 34 0 R /F9 35 0 R /F10 37 0 R /F11 39 0 R >> /XObject << /Im1 48 0 R /Im2 49 0 R >> /ExtGState << /GS1 42 0 R >> /ColorSpace << /Cs5 30 0 R >> >> endobj 24 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 181 /Widths [ 482 482 334 964 964 1333 1087 272 370 370 592 600 482 444 482 370 964 964 964 964 964 964 964 964 964 964 482 482 600 600 600 791 800 1012 1012 1012 1061 864 839 1061 1042 296 791 987 765 1332 1087 1087 939 1087 987 987 864 1042 964 1332 1012 964 913 370 370 370 600 500 272 765 791 741 791 765 494 791 791 272 272 716 272 1235 791 815 791 791 642 765 593 791 690 1042 690 667 667 370 222 370 600 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 482 964 964 482 482 482 482 482 800 482 482 482 482 482 482 482 600 482 482 482 791 ] /Encoding /WinAnsiEncoding /BaseFont /JLJKLF+Eurostile-ExtendedTwo /FontDescriptor 26 0 R >> endobj 25 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 240 /Widths [ 250 333 408 500 500 833 778 180 333 333 500 564 250 333 250 278 500 500 500 500 500 500 500 500 500 500 278 278 564 564 564 444 921 722 667 667 722 611 556 722 722 333 389 722 611 889 722 722 556 722 667 556 611 722 722 944 722 722 611 333 278 333 469 500 333 444 500 444 500 444 333 500 500 278 278 500 278 778 500 500 500 500 333 389 278 500 500 722 500 500 444 480 200 480 541 250 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 500 500 0 0 0 0 0 760 0 0 0 250 0 0 250 564 250 250 0 500 250 250 250 250 250 0 0 250 0 0 0 0 0 250 0 250 250 0 0 0 250 0 0 0 0 0 500 1000 444 444 0 0 0 250 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 250 ] /Encoding /MacRomanEncoding /BaseFont /JLJNFE+TimesNewRomanPS /FontDescriptor 28 0 R >> endobj 26 0 obj << /Type /FontDescriptor /Ascent 705 /CapHeight 705 /Descent -225 /Flags 32 /FontBBox [ -221 -279 1326 1042 ] /FontName /JLJKLF+Eurostile-ExtendedTwo /ItalicAngle 0 /StemV 190 /XHeight 465 /CharSet (/u/k/m/l/P/o/c/D/comma/y/p/x/e/S/d/F/f/a/E/r/space/h/g/s/i/t/n) /FontFile3 40 0 R >> endobj 27 0 obj << /Type /FontDescriptor /Ascent 705 /CapHeight 705 /Descent -225 /Flags 262176 /FontBBox [ -60 -250 1270 993 ] /FontName /JLJLKB+Eurostile-Demi /ItalicAngle 0 /StemV 126 /XHeight 465 /CharSet (/u/d/Y/F/f/I/E/period/h/J/P/w/i/L/y/x/zero/M/n/one/H/k/O/two/m/l/g/three\ /o/A/R/parenleft/p/four/S/parenright/five/bullet/U/B/a/r/space/V/b/C/K/N\ /s/W/c/D/T/comma/t/eight/X/e/G/hyphen) /FontFile3 41 0 R >> endobj 28 0 obj << /Type /FontDescriptor /Ascent 705 /CapHeight 705 /Descent -225 /Flags 34 /FontBBox [ -167 -216 1009 878 ] /FontName /JLJNFE+TimesNewRomanPS /ItalicAngle 0 /StemV 87 /XHeight 465 /CharSet (/u/d/nine/F/f/I/quotedblright/v/E/period/h/colon/J/P/w/slash/semicolon/i\ /L/endash/percent/y/x/zero/j/M/n/less/z/one/k/H/O/two/m/l/g/three/o/pare\ nleft/A/R/p/four/S/parenright/quotedblleft/q/five/U/emdash/B/a/r/space/s\ ix/b/V/C/K/s/seven/W/c/N/D/comma/T/t/eight/e/G/hyphen) /FontFile3 45 0 R >> endobj 29 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 240 /Widths [ 352 309 474 705 705 905 781 238 348 348 705 584 352 266 352 682 705 705 705 705 705 705 705 705 705 705 352 352 584 584 584 595 975 709 716 696 754 619 582 727 769 276 583 715 565 1007 827 715 686 766 722 673 587 754 677 1113 693 670 648 348 278 348 584 500 371 589 594 551 593 570 348 594 598 236 225 539 252 924 598 582 596 597 471 557 425 593 491 796 500 485 475 389 280 389 584 352 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 705 705 0 520 0 0 0 790 0 0 0 352 0 0 352 584 352 352 0 593 352 352 352 352 352 0 0 352 0 0 0 0 0 352 0 352 352 0 0 0 352 0 0 0 0 0 0 0 0 0 0 0 0 352 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 352 ] /Encoding /MacRomanEncoding /BaseFont /JLJLKB+Eurostile-Demi /FontDescriptor 27 0 R >> endobj 30 0 obj [ /CalRGB << /WhitePoint [ 0.9505 1 1.089 ] /Gamma [ 2.2222 2.2222 2.2222 ] /Matrix [ 0.4124 0.2126 0.0193 0.3576 0.7152 0.1192 0.1805 0.0722 0.9505 ] >> ] endobj 31 0 obj << /Length 2712 /Filter /FlateDecode >> stream Expansion is achieved by virtue of small amounts of gas contained within the polystyrene bead.
