Supplying the Automotive Sector

CB Frost & Co manufactures a range of products from sponge/rubber die cut gaskets to rubber mouldings and extrusions for a variety of industries including Automotive.

Our products offer lightweight, functionality and durability for numerous automotive applications. They exhibit energy absorbency properties, long life durability, low odour, low fogging and low VOC.

Zotefoams is a major manufacturer of closed cell foam, damping, sealing and insulation materials for the automotive manufacturing industry. The days of using foam materials only to address NVH concerns are long gone. Functional foam components, used throughout the vehicle, including the engine compartment, now provide light weight, cost effective solutions that help reduce CO2 emissions and increase fuel efficiency. Physically expanded in an open environment using pure nitrogen, these foams are pure and relatively stress free with an exceptionally regular cell size and structure. CB Frost are experts at converting this material into a variety of solutions.

Volatile Organic Compounds (VOC’s) are causes of both Fogging and Odour. The Zotefoams manufacturing process uses only nitrogen gas as the foaming agent for their thermoplastic foam products. The absence of chemical foaming agents removes a major potential source of VOC’s in foams. Zotefoams materials have been analysed in accordance with various standards including VDA 277 and VDA 278.

Chemical contamination or volatile additives or constituents in the polymeric materials are the most common source of “fog” or chemicals in new cars. Being by nature highly pure, both AZOTE and ZOTEK foams have low fogging tendencies. Representative samples have been tested to determine their windscreen fogging characteristics according to DIN 75201 Methods A & B with excellent results

To limit the negative effects of “new car smell” caused by new materials car manufacturers have created test methods to attempt to quantify what is essentially a subjective judgement. Zotefoams materials have been tested to various standards including VDA 270 achieving at least classification C3.

Zotefoams materials have been tested to FMVSS 302 – the flammability standard adopted by the majority of vehicle manufacturers. Zotefoams materials will meet the requirements of this test once the foam part is above a minimum area weight. Superior performance is achieved by the inclusion of flame-retardant additives. These grades will meet the requirements with a self-extinguish rating

Why our products are ideal for Automotives:

Weather sealing
Vibration isolation
High and low temperature resistance
Water and oil resistant
Durable over time
Highly mouldable
