For applications requiring long-lasting tackiness, outstanding flexibility, and highly efficient lubrication performance, Polyisobutylene (PIB) may be the ideal solution.
Polyisobutylene (PIB) is a synthetic polymer produced through the catalytic polymerization of high-purity C4 hydrocarbon feedstock with a high isobutylene content. The resulting product is a transparent, odorless, chemically stable, and non-toxic liquid polymer with exceptional physicochemical properties.
With a number-average molecular weight (Mn) ranging from 300 to 4000 g/mol, PIB is widely recognized for its excellent tackiness, oxidation resistance, and low permeability to moisture and gases. These outstanding characteristics have made it a preferred material for engineers and manufacturers worldwide across a broad range of applications, including adhesives, sealants, rubber compounds, stretch films, lubricants, greases, and metalworking fluids.

Braskem Polyisobutylene (PIB) fully complies with U.S. Food and Drug Administration (FDA) food-contact regulations and is NSF certified, making it suitable for safe use in food-related packaging applications.

We are committed to providing our customers with high-quality products and exceptional service.

Alternative to Traditional Raw Materials
Can replace conventional process oils while functioning as both an extender and plasticizer, optimizing formulation cost and performance.
Enhanced Material Performance
Effectively improves cold-flow properties, impact resistance, and stress-crack resistance, while also enhancing processing efficiency for more stable production.
Broad Compatibility
Fully compatible with a wide range of rubber and plastic substrates, including EPDM, SBS, SEBS, SBR, butyl rubber, and polyisoprene, making it suitable for diverse application requirements.

Core Functionality
Used as a cling agent in agricultural stretch films and pallet stretch wrap films, providing reliable self-adhesive performance.
Performance Enhancement
Improves film gloss, barrier properties, and processing flowability, helping manufacturers produce higher-quality film products.
Efficient Production Compatibility
PIB32 Polyisobutylene (PIB) can develop a stable cling layer within 48 hours in Linear Low-Density Polyethylene (LLDPE) films, supporting efficient production scheduling and consistent manufacturing performance.
Value-Driven Performance
Proper use of PIB helps reduce film breakage during application, significantly improving packaging efficiency while lowering operational costs.

Excellent Viscosity-Temperature Performance
Effectively lowers the pour point of lubricants at temperatures as low as -40°C, ensuring smooth equipment start-up in cold environments. Under high-temperature conditions up to 150°C, it maintains stable viscosity to prevent lubrication failure, making it suitable for wide temperature operating ranges.
Enhanced Lubrication Protection
The long-chain hydrocarbon structure forms a dense protective film on metal friction surfaces, significantly reducing friction and component wear while extending equipment service life—particularly in high-load transmission systems.
Outstanding Chemical Stability
Offers excellent oxidation and hydrolysis resistance, with superior compatibility with mineral oils, synthetic base oils, antioxidants, and extreme-pressure additives. It does not generate sludge or deposits, ensuring long-term storage and operational stability of lubricants and greases.
Wide Range of Applications
Can be used as a base oil or viscosity index improver in automotive engine oils, industrial gear oils, and bearing greases, as well as in specialty applications such as lubricants for medical devices and food-grade machinery.

Texture Enhancement
Improves the spreadability of lipsticks and lip glosses to prevent creasing, while enhancing the moisturizing feel of creams and lotions without leaving a greasy residue—suitable for a wide range of skin types.
Long-Lasting Film Formation
Forms a lightweight, breathable film on the skin and lips to help lock in moisture, extend makeup wear time, and improve the water and sweat resistance of products such as mascara without compromising skin comfort.
Excellent Compatibility & Safety
Highly compatible with oils, waxes, pigments, and other cosmetic ingredients without causing separation or sedimentation. With low irritation potential and compliance with safety standards, it is suitable for sensitive-skin formulations.
Wide Range of Applications
Ideal for lipsticks, lip glosses, mascaras, creams, lotions, and sunscreens, as well as hair care products such as hair oils and styling waxes to nourish hair and reduce frizz.

Designed with skin-friendly materials and reliable adhesion, the products provide secure fixation while minimizing skin irritation. Soft and breathable construction ensures comfort during extended wear, making them suitable for daily medical and personal care applications.
Offers strong holding power to keep dressings, tubing, and protective coverings firmly in place. At the same time, the adhesive system allows for clean and painless removal with minimal residue, helping protect delicate or sensitive skin.
