TPC Group TPC 1160 Enhanced Grade Polyisobutylene
Categories: Polymer

Material Notes: Characteristics: TPC offers enhanced grades of polyisobutylene (PIB), which are replacements for conventional grades of PIB in applications where viscosity and tackiness are desired key qualities. Our proprietary process produces clear, consistent and water white products in a variety of molecular weights and viscosities.

Applications: TPC 1160 can be used for a variety of applications such as: Cosmetics, pressure sensitive adhesives, hot melt adhesives, water based adhesives, automotive sealants, window sealants, tire sealants, viscosity modifiers, tackifiers, PIBSA reactions, emulsions, asphalt/bitumen, elastomer based sealants and caulks, polymer modification, adhesives, cling film, gum base, rubber modifier, roofing membranes. TPC 1160 has a viscosity range of 625 – 685 cSt with a molecular weight of 1600.

General: Enhanded PIB grades are used as replacements for conventional grades of PIB. Enhanced PIB grades are ideal for applications where viscosity and tackiness are key qualities of the material. TPC Group offers the broadest portfolio of PIB products to the market and is a major supplier to many different markets, including fuels and lubricants, caulks, sealants, adhesives, packaging, greases and emulifiers.

Packaging: These grades are typically sold in railcar quantities but isocontainers and trucks are also available.
