Conductive Cross-linked Polyethylene Foam LD50CN High Density Closed Cell Cross-linked Conductive Polyethylene, EV45CN (EVA Copolymer Conductive) Foams:
* are inert and lightweight
* are tough, flexible and resilient
* are highly energy absorbent
* are easily fabricated using well known techniques
* are easy to thermoform using standard vacuum forming or heat impression molding techniques
* have a very wide operating temperature range
* exhibit excellent chemical and water resistance
* do not cause staining of paint finishes
* do not corrode metal parts
* exhibit good U.V. stability

Zotefoams Inc. products are made by a unique high pressure nitrogen gas solution process.

The superiority of these products, compared with polyethylene foams made by other technologies, stems directly from the use of this high pressure gas technology.

This produces a pure, chemically inert foam without blowing agent residues and with a uniform cell structure and regular cell walls. The process comprises three main stages

Product Advantages
The unique manufacturing process results in arrange of unique properties which, in turn, can help to differentiate the finished product from those made using other foams

Some examples of these properties translating into applications are discussed below;

A Very Pure Product
Because there is no chemical blowing agent used, the resultant foam product is very pure. This gives rise to the following

Biologically inert	important for health care applications
Very low fogging	important in optic applications
Does not smell	Helpful for all production
Ammonia free	Some packaged products are sensitive to ammonia contamination. Our foam products are ammonia free

Very Regular Cell Structure With Minimal Density Variation
This means that designers do not need to over specify in order to take account of density variations within the sheet. this therefore implies;

Lighter foam	This is valued in cushion packaging where weight savings can be vital.
Predictable properties	Important when designing molded components or packaging sensitive products.
*Stronger foam*	Density for density our foams are tougher and stronger than other foams. This is appreciated in most applications where performance is part of the specifications.
