TPC Group TPC 595 Highly Reactive-Grade Polyisobutylene
Categories: Polymer

Material Notes: Characteristics: TPC 595 is colorless (water white), has very low moisture transition rates, is non-corrosive, can be used for emulsions and is hydrophobic with a molecular weight of 1000. TPC 595 is a highly reactive (HR) grade polyisobutylene (HRPIB), which means that greater than 80% of its double bonds are in the terminal position of the molecule (alpha).

Applications: TPC 595 can be used for a variety of applications such as: A replacement for bright stocks, mineral oils and process oils, cosmetics, PIBSA reactions, emulsions, fuel and lubricant additives, 2 stroke engine oil, viscosity modifiers, pour point depressants, corrosion inhibitors, tackifiers, asphalt/bitumen, polymer modification, adhesives and elastomer based sealants and caulks and PIBSA reactions.

General: HR-PIB is especially valued in the fuel and lubricant market as it delivers improved end product performance to the consumer and better manufacturing economics for the additive supplier. Processing with HR-PIB also produces less char during manufacture and the derivative products are used to improve funal lubricant and fuel performance. 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: TPC 595 is typically sold in railcar quantities, but trucks and isocontainers are also available.
