Trekollan® – An extremely flexible material system

TREKOLLAN® – A VERY FLEXIBLE MATERIAL SYSTEM

Trekollan® is our polyurethane material manufactured at our production facility in Traryd. With our Trekollan® materials, we offer polyurethane with very good properties. In Traryd we have a very flexible facility where we quickly can switch between our different material qualities.

Today we deliver Trekollan® grades between 25 Shore A – 60 Shore D.

MANUFACTURING PROCESS

The material is a cross-linked elastomer which, depending on the quality, can consist of ester or ether polyols and diisocyanates (MDI – diphenylmethane diisocyanate) or (TDI – toluene diisocyanate) where the production is done in several steps by chemical reactions. The manufacturing process is very meticulous and is carried out either through a mixing machine or a hand mixing process that makes us extremely flexible. Regardless of material quality, a post-curing of the material is required at about 110 ° C for at least 16 hours.

MATERIAL PROPERTIES

TREKOLLAN® HAS A LOT OF AMAZING PROPERTIES.

The qualities based on ester polyol are characterized by very high abrasion resistance and tear strength. Suitable applications can be: Scrapers, wear plates, concrete linings, damping washers, plough cutters etc.

The grades based on ether polyol are characterized by good hydrolysis resistance, low heat build-up and bounce elasticity. Suitable applications can be in environments where the material is exposed to heat and water, e.g. washing equipment, blaster protection (large angle of incidence), wheels (low heat build-up) etc.

There are also very suitable materials for application roller (paint roller) with very good solvent resistance as well as material with FDA approval for food handling.
