Butyl Rubber Vistanex L-100 from China
Vistanex L-100 is a high molecular weight elastomeric polyisobutylene with over 95% isobutylene content, imported in primary pellet form under HTS 3902.20.10.00. Known for tackiness, it serves as a pressure-sensitive adhesive base in tapes and sealants. Its elastomeric nature distinguishes it from rigid polyolefins.

Import Tips
• Submit manufacturer's spec sheets confirming elastomeric grade and 95%+ monomer purity
• Watch for reclassification if blended polymers predominate other monomers
• Use proper UN packaging for sticky polymers to prevent shipping issues
