A dense, self-formed outer skin. A cushioning foam core. No lamination, no glue line, no assembly. Just the most versatile molded urethane product engineers specify.
When a reactive polyurethane system meets the heated mold wall, the exothermic reaction at the surface proceeds differently than it does at the part's warmer interior. The surface gels quickly with minimal cell formation, producing a dense continuous layer. The interior gels more slowly, allowing blowing agent expansion to develop a cellular structure. The result, out of one mold in one pour, is a part with a smooth tough skin and a compliant foam core — chemically continuous, no interface, no bond to fail. We use non-ozone-depleting pentane as the blowing agent, which improves cell uniformity and skin formation consistency compared to water-blown systems.
The skin replicates mold surface finish — from high-gloss to leather-textured. No paint, no powder coat, no secondary coating. Molded-in color eliminates another step. The surface is maintenance-free — no upholstery to replace, no coating to re-apply. A part comes out of the mold and goes into the box.
The skin gives the part rigidity and toughness where it matters — at the surface the user touches. The foam core absorbs impact and conforms under load. You get a part that feels solid and cushions like foam, simultaneously.
A glued-on skin over a foam core has two failure modes: the skin tears or the bond separates. Integral skin has one continuous material. When it wears, it wears gracefully — no delamination, no skin lift, no ugly failure mode.
Integrated bosses, undercuts, threaded-insert locations, and textured grip zones all form in one mold cycle. Parts that used to be 3-piece assemblies become single parts, often at lower cost.
Surgical instrument handles, handheld diagnostic grips, imaging probe housings — durable skin, comfortable core, sterilization-compatible.
Operator cab padding, armrests, and equipment housings for forklifts and industrial equipment, plus shock-absorbing tool grips and vibration-damped controls requiring soft-touch skin with dimensional consistency.
Soft-touch interior surfaces where feel, durability, and molded-in geometry all matter. Classic integral-skin application since the 1980s.
Molded-in color and texture eliminate upholstery. Extremely durable for office and institutional seating applications.
Weather-resistant integral-skin compounds for outdoor and athletic applications requiring long-term UV exposure.
