Sponge rubber punched parts

We mostly use punched parts from sponge rubber as seals or sound insulation components. They are also often used in the storage area, e.g. when particularly elastic storage material is needed. Additionally, sponge rubber punched parts are very good impact and slip protection and prevent damage from vibrations and shock. Thanks to their diverse uses, sponge rubber punched parts are used in many different industries. The most frequent industries include vehicle construction and the electronics industry, as well as engineering and device construction or the large area of sanitary, ventilation and air conditioning technology.

Sponge rubber - a special material

Sponge rubber is a mixed-cell rubber that is made of natural or synthetically produced rubber. Why it is special: while its outer skin is tight, sponge rubber has a spongy, porous structure on the inside. The already-mentioned outstanding sealing properties are complemented by other positive properties: the outer form of sponge rubber can be influenced well by punching or cutting. Additionally, the material is characterised by high elastic softness and dimensional stability.

KKT offers sponge rubber punched parts in nearly any form. All punched parts, as well as any other sponge rubber products, are also available with one self-adhesive side. By default, our sponge rubber punched parts are approx. 15° shore A. Contact us if you need any other strengths.
