Product Description
Catalyst PS/2LR is a PE based catalyst masterbatch, which accelerates the crosslinking reaction of the pipe product during its curing process that can take place by exposure of the pipe to water or steam at high temperature. Catalyst PS/2LR contains a processing aid and a lower reactive agent which in certain conditions improves processing

Use and Dosage

Catalyst PS/2LR shall be used together with the silane-crosslinkable POLIDAN® compounds in the ratio of 5 to 95 parts respectively. The two components shall be mixed together before the extrusion or continuously during the process with the use of automatic feeders. Usually there is no need to pre-dry the catalyst masterbatch.


Colouring

Catalyst PS/2LR and POLIDAN® compounds can be used with good quality PE based colour masterbatches. Solvay Specialty Polymers suggests to pre-dry any colour masterbatches prior to use.


Storage

The product shall be stored under the following conditions:
  • Closed and unbroken bags
  • Ambient temperature not exceeding 40°C
  • Indoor in order to avoid direct exposure to sunlight

The product could undergo alterations due to extended period of storage. Solvay Specialty Polymers suggests the product use within 12 months from the production date printed on the packaging. Solvay Specialty Polymers accepts no liability of any kind in case the above mentioned conditions are not fulfilled.

Packaging

Catalyst PS/2LR is supplied in 25 kg bags placed on pallets.
