New NBR Grade with Excellent Dimensional Stability from ARLANXEO

Published on 2016-10-26. Author : SpecialChem

DÜSSELDORF -- ARLANXEO has launched a new nitrile butadiene rubber (NBR) grade to meet the requirements of high-end customers.

Krynac® XL 3375 VP NBR Rubber


  • Krynac® XL 3375 VP is a new pre-crosslinked NBR, specifically developed to deliver high quality products with no compromise on production efficiency. 
  • It is particularly suited for extruded and calendered parts requiring good dimensional stability, such as hoses inner parts, rubber linings, semi-finished products, belts.
  • Other key processing benefits include good calendering behavior, low shrinkage, smooth compound surface and higher compound green strength. 
  • Moreover, Krynac® XL 3375 VP delivers reduced nerviness on the mill.

Hose Compound Made of Different Rubbers

The pre-crosslinked structure of the new Krynac® XL 3375 VP allows exceptional performance in terms of mechanical properties such as elongation at break and tensile strength as well as extremely low compression set values.

Krynac® XL 3375 VP can be used either pure for best extrusion and calendering stability or blended with linear Perbunan or Krynac grades in order to increase gradually dimensional stability. Replacing 25 parts of linear grade with this pre-crosslinked NBR will already give excellent performance in processing.

Food Contact Approval


Krynac® XL 3375 VP is approved for food contact applications (FDA CFR §21 177.2600 and BfR XXI). This makes Krynac® XL ideally suited for the production of hoses to transport liquid as well as solid foodstuff like vegetable oil, milk, wine, beer, sugar, etc.

Krynac is a product of the business unit High Performance Elastomers.
