The special features of EVA

Ethylene vinyl acetate (EVA) is the copolymer of ethylene and vinyl acetate. EVA is an elastic material which can be sintered and thereby form a porous material. It resembles rubber, but it is extremely resistant. It is three times as flexible as polyethylene (LDPE) with a tensile elongation of 750%.

This material has a high level of toughness at low temperatures.
In addition, it is resistant to stress cracking and is resistant to water and UV radiation.

EVA has little or no smell.

We manufacture profiles made from EVA, not PVC.

The special features of liquid silicone rubber (LSR)

(LSR = Liquid Silicone Rubber) In contrast to the peroxidically cross-linked solid silicones, liquid silicones are addition crosslinked. When processing in the injection moulding process, 2 ready-for-use individual components are mixed in the ratio 1: 1 and injected into the hot vulcanizing mould.

The processing of LSR can take place with low injection pressures whereby, as a result, burr-free production of the mouldings is usually possible.

The liquid silicone rubbers therefore exhibit high temperature resistance, very good flexibility in cold environments, excellent ageing characteristics and excellent electrical insulation properties. In addition, they have a good resistance to tear propagation and high tensile elongation.

LSR has the hardness of liquid silicone, 30-80 Shore.

Areas of application: Due to high physiological compatibility, many mouldings can be made from liquid silicone in the field of medical technology. Special, highly transparent types are suitable for optical applications (e.g. contact lenses).
