Please note that nothing on this site has been designed or tested for large scale manufacturing or re-sale, and attempting to sell anything made from recipes on this website is a bit foolish and at your own risk. Note: Polybutene is essentially isobutene and butene copolymer, but mainly to isobutene, it is different from Poly 1 - butene, and Polyisobutene similar. Polybutene can shrink more if it is cooled down further or subject to greater pressure. According to CTFA (2006b), laboratory tests with approved surrogate systems/animals revealed that skin contact testing showed only slight irritation (primary dermal irritation score [PDIS] of 1.5/8.0). Polybutene films have a high resistance to stress cracking, and low stress deformation. The availability of polybutene at a variety of molecular weights provides the ability to fine-tune property improvements.
