Polyisobutylene (PIB)

Looking for a smart solution for long-lasting tack, flexibility, or effective lubrication in oils and greases? Polyisobutylene (PIB) could be exactly what you need.

PIB is a synthetic polymer produced through catalytic polymerization of a highly pure C4 hydrocarbon stream with a high isobutylene content. The result? A clear, odorless, chemically stable, and non-toxic liquid polymer with exceptional physico-chemical properties.

Available in a wide molecular weight range (Mn from 300 to 4,000 g/mol), PIB is renowned for its excellent tack, oxidation resistance, and low moisture and gas permeability. That’s why engineers and manufacturers worldwide rely on PIB in a variety of applications, including adhesives, sealants, rubber compounds, stretch films, and lubricants, greases, and metalworking fluids.

Applications & Benefits of PIB

Adhesives & Sealants

Delivers permanent tack and flexibility down to -60°C
Functions as a tackifier, rheology modifier, ánd extender
Compatible with various resins such as rosin esters and hydrocarbon resins
Ideal for: butyl tapes, hotmelt pressure-sensitive adhesives, sealants, automotive tape, and food packaging
- Did you know PIB is fully compliant with FDA food-contact standards?

Stretch Films (LLDPE)

Used as a cling agent in agricultural and pallet stretch wrap
Improves gloss, barrier properties, and processability
PIB 32 develops a stable cling layer in LLDPE films within 48 hours – perfectly aligned with your production planning
- Smarter use of PIB = less damage, greater efficiency

Rubber & Plastic Compounds

Replaces process oils as an extender and plasticizer
Enhances cold flow, impact resistance, stress crack resistance, and processability
Fully compatible with EPDM, SBS, SEBS, SBR, butyl rubber, and polyisoprene

Additional Uses

Viscosity index improver polymer in lubricants
Applied in coatings, paper impregnation, metal processing, and even agriculture

Available Product Grades

We offer a complete range of PIB grades, including:

PIB 4, 6, 10, 12
PIB 24, 28, 30, 32
PIB 128 (higher viscosity, longer tack time)

Each grade differs in molecular weight and rheological properties, tailored to your specific application. For example:

PIB 32: Fast migration, high final tack – ideal for stretch film
PIB 128: Slower diffusion, longer processability – ideal for rubber and plastic compounding

Not sure which grade suits your formulation? Just ask – we’ll help you make the right choice.
