Polyurethane Elastomer Raw Materials for High Resilience Pulley Composition

Product Overview

Description

 

Polyurethane Elastomer Raw Materials for High Resilience Pulley Composition

Composition  It consists of two components, component A is polyols, component B is performed polymer end capping by isocynate.

Characteristics

Blend temperature: 5060; Vulcanization temperature: 7080;Demould time:20~30min (regulated by catalyst),with

Attentions

Put APand BI into bucket, then pour them into mould after vacuum degassing. Put pigment into A while regulating colors. After putting pigment into A, pay attention to sealed storage A/B, avoid absorbing moisture and going bad.

 Application

 It applies to produce roller skates wheel, skateboard wheel, inline skates wheel etc.

Storage

Store in cool and dry place. If you cant use it up at a time, filling nitrogen gas and sealing it, otherwise it will easily absorb moisture and go bad. The storage time of original binding is 3 months.  

 Packing

200Kg galvanization iron drum
