BK
Rubber Foaming Accelerator
CAS No: 10396-10-8
Melecular Weight: 229.2563
BK is obtained by a reaction of urea with organic acids under specific conditions, suitable for PVC/NBR, variousrubbers, and rubber-like foam vulcanization products. lt enhances vulcanization, reduces accelerator usageabsorbs odors like ammonia and formaldehyde, and ensures a uniform pore structure, addressing non-compact anduneven foam issues.
Woven bags with inner plastic film (customized as required) ,25kg/bag, should be stored in a well-ventilated, dry place, away from heat sources and open flame.
