PIB Polyisobutylene Adhesive 1300 Viscosity Index Improver Additives PIB1300
Ultra-High Tack Pressure-Sensitive Adhesive Polymer
PIB1300 is a premium PIB polyisobutylene adhesive with stable chemical properties. This non-volatile liquid will not form residues after high-temperature volatilization or thermal decomposition. This specialized PIB polyisobutylene adhesive has excellent thermal oxidation performance, is impermeable to water vapor and other gases, is hydrophobic, and has good shear resistance.
- Exceptional thermal oxidation performance
- Impermeable to water vapor and gases
- Hydrophobic properties
- Superior shear resistance
- No residue formation after high-temperature exposure
PIB1300 can be used for hydraulic oil, gear oil, drawing oil, quenching oil and as a thickener for various materials.
Product Introduction
PIB1300 is a medium molecular weight polyisobutylene (Mn: 1200-1375) engineered for premium pressure-sensitive adhesives requiring exceptional tack, cohesion, and aging resistance. With controlled molecular architecture and narrow polydispersity (PDI ≤1.5), it delivers superior bond strength across extreme temperatures (-40°C to 120°C) while maintaining REACH/ECHA compliance. Critical applications include medical tapes, industrial labels, and automotive vibration damping systems.
Advanced Features
- Permanent Tack Performance
Initial tack >20 N/25mm (FINAT FTM 9) with zero residue upon removal.
- Thermal Endurance
SAFT ≥125°C (ASTM D4498) and cold temperature flexibility down to -50°C.
- Oxidation Resistance
≤0.5% weight loss after 1,000h @ 85°C (ASTM D5721), preventing adhesive hardening.
- Medical-Grade Safety
USP Class VI certified, ISO 10993 biocompatible, and free of BPA/phthalates.
- Universal Compatibility
Blends seamlessly with SIS/SBS hotmelts, acrylics, and rubber resins.
