This is available in a range of molecular weights from approximately 1050 to 2400.

PIBSA Based Crankcase Additives

For engine oil additives, PIBSA is considered to be one of the primary precursors used to build additives. Nelson Brothers typically works with 1000 to 2300 molecular weight polyisobutylene succinic anhydride (PIBSA) based engine oil additives. This molecular weight range is selected to provide the properties necessary to withstand the demanding conditions required for products used in these applications.

Nelson Brothers polyisobutylene succinic anhydride (PIBSA) is produced using polyisobutylene (PIB) that has been produced via the thermal process and therefore there is no residual chlorine present. Nelson Brothers products are predominantly produced from highly reactive polyisobutylene (HR PIB), however products based on conventional polyisobutylene can also be produced if required by the customer. Nelson Brothers Specialty Chemicals offers laboratory size samples of products to prospective customers free of charge.
