SP/PA Rubber (Super Processing/Processing Aid Rubber)
John Woon (Senior Latex Consultant): SP and PA stand for "Super Processing" rubber and "Processing Aid" rubber respectively.
These rubbers were developed by RRIM in Malaysia more than 50 years ago. The rubber was initially made in the form of sheets in 1950’s. With the advent of SMR Scheme in block form in 1960’s, block form of SP/PA started to be produced.
These were made by blending prevulcanised latex with unvulcanised latex concentrate to ensure good homogeneity. Different mix ratios are being used to make, for instance, SP20, SP40, and SP50 with the number indicating the percentage of vulcanized rubber.
PA rubbers are the more “concentrated” versions of SP. Examples are PA80 with 80% vulcanized rubber and PA57 (This is PA80 with added non-staining naphthenic oil).
