INTEGRAL SKIN FOAM POLYURETHANE SYSTEMS

BayOne integral skin foam systems combine the advantage of a durable non-porous outer elastomeric skin with a low-density cellular core. The tough-yet-flexible outer skin provides excellent resistance to abrasion, cutting, puncture, and chemical attack, while the foam core makes finished parts weigh less so they are more cost-efficient than those made with a solid non-cellular material.

Systems Available

HFC-245fa / Pentane-Blown: for parts requiring a thicker skin and a firm core
HFC-134a and Water Co-Blown: for parts requiring a soft, resilient hand
Water-Blown: for parts requiring uniform physical properties through the cross-section

Physical Property and Process Requirements

Hardness from 70 Shore OO to 85 Shore A
Free rise density from 5 pcf to 15 pcf
Molded density from 12 pcf to 30 pcf
Cream time from 15 seconds to 60 seconds
De-mold time as low as 5 minutes

Performance Considerations

Hardness versus density
In-mold coatings for color matching and light fastness/color stability
Hand or machine mixed
Injection point, mold venting and parting lines
Enhanced flow for complex parts or those having thin cross-sections
Need for high elongation or excellent cut-tear resistance
Ability to heat and maintain mold temperature from 105°F to 135°F
