The automotive industry uses thermoset polyurethanes for prototypes and initial parts to reap the benefits of lightweight with excellent durability.  Advanced polyurethanes are tough enough for use in high-heat, under-hood applications, “A” and “B” pillar prototyping, automotive interior components, exterior fascias and claddings, grilles, headlight bezels and aftermarket parts.  Polyurethane elastomers produce gaskets and seals, padding and wire harnesses.  Water clear polyurethanes exhibit outstanding clarity for molding lenses, pillow optics and tail lights.  Polyurethane foams are used to absorb energy and sound and are installed under instrument panel surface skins.

Throughout today’s vehicles, polyurethanes, including advanced products from Innovative Polymers, are supporting the manufacture and marketing of new automobile designs and the ultimate production of safer, quieter, longer-lasting components.

Innovative Polymers manufactures many different polyurethanes for automotive applications.  Among the products most frequently chosen by automotive companies and their suppliers are:

• Shore A Elastomers have gel times from 10 to 25 minutes.  The product line includes clear systems as well as cream, off-white and amber colored products.  Polymers exhibit good tear strength for automotive interior padding and are tough enough for casting of wire harnesses, bumpers and model tires
• Rapid Cast, Fast Cure Polyurethanes gel in seconds and are designed for automated meter/mix dispensing.  The Shore D hardness systems include water clear products, high flexural modulus (350,000 psi) materials and polymers with high heat capabilities that can withstand exposure to temperatures up to 284ºF (140ºC) without a post-cure.
• High Performance Polyurethanes simulate polypropylene, TPO and ABS thermoplastics.  The Innovative Polymers materials, based on advanced crosslinked technologies, combine ultra-high impact strength with medium-to-high flexural modulus values and high heat resistance.  A flame retardant system that meets UL 94 V-O standards is also available.
• Vacuum Assisted Casting Polyurethanes include water clear, tan, off-white and translucent products.  The Shore A hardness materials have good elongation and tear strength.  The Shore D hardness systems have high to ultra-high flexural modulus values as well as good elevated temperature performance.
