Neopolen P 9335 mg

Thermal Insulation in Designer Clothing

Neopolen P 9335 mg

Since a short time ago, BASF SE, Ludwigshafen, Germany, has been offering a new and patented type of Neopolen P foam (EPP: expanded polypropylene) for equipment used in heating, ventilation and plumbing applications. The metallic gray Neopolen P 9335 mg exhibits up to 10 % better thermal insulating characteristics than standard EPP. Because of the versatile characteristics of this new product, foamed Neopolen P molded parts can fulfill several functions simultaneously: This foam can serve as an efficient, impact-absorbing packaging material for shipping, be designed for use as an equipment carrier and even replace the actual metal housing, since it can be processed into a thermally insulating enclosure with anesthetic surface. The newly developed EPP foam thus helps to comply with the energy standards for low-energy residential housing construction and building renovation.

It also provides new design opportunities for equipment such as heat exchangers and solar reservoirs. Neopolen P 9335 mg can be used to produce strong, elastic foam parts that can replace the previously required metal or injection molded enclosures. Undercuts can be created in the molded parts simply and cost effectively without the need for complex mold designs. This gives the designer new opportunities to incorporate additional functions such as ventilation ducts or equipment fixation points in the enclosure. In this way, the number of components needed can be reduced to a minimum. The heating or electronic component is held securely directly in the tough, elastic Neopolen P-enclosure and protected against damaged during shipping.

In use, the equipment then also has efficient thermal insulation at the same time. The polymer matrix of Neopolen P 9335 mg contains infrared absorbers that reflect thermal radiation like a mirror and in this way reduce thermal conduction considerably below that of conventional EPP. Neopolen P is temperature resistant over a range of -40°C to +100°C.

Thanks to new mold technologies, the foam can be processed in a way that yields high-quality surfaces without the typical foamed particle appearance and nozzle impressions. The uniformly expanding foam beads conform to the modified surface of the mold, creating a homogeneous, aesthetic surface appearance, e.g. with the look of leather.
