Manufacturer Adhesives and Sealants CAS 9003-27-4 Polyisobutylene PIB

 

 

Polyisobutylene (PIB) is a synthetic polymer with the CAS number 9003-27-4. Here's a description, technical data, and application of Polyisobutylene (PIB):

 

Description:

Polyisobutylene (PIB) is a versatile elastomer that belongs to the class of polyolefins. It is a high molecular weight polymer composed of repeating units of isobutylene. PIB is typically a viscous liquid or a soft solid with rubber-like properties. It is chemically inert, non-toxic, and resistant to heat, moisture, and chemicals.

 

Technical Data:

The technical data for Polyisobutylene (PIB) can vary depending on the specific grade and manufacturer. However, here are some general technical properties associated with PIB:

• Molecular Weight: PIB can have a wide range of molecular weights, ranging from a few thousand to several million grams per mole.
• Density: The density of PIB typically ranges from 0.88 to 0.92 g/cm³.
• Viscosity: PIB exhibits a wide range of viscosities, from low-viscosity liquids to high-viscosity semi-solids or solids.
• Glass Transition Temperature (Tg): PIB has a low glass transition temperature, typically below -60°C (-76°F).
• Chemical Resistance: PIB is resistant to many chemicals, oils, and solvents.
• Impermeability: PIB has excellent gas barrier properties, making it suitable for applications requiring gas impermeability.
• Thermal Stability: PIB has good thermal stability and can withstand high temperatures without significant degradation.

Application:

Polyisobutylene (PIB) finds application in various industries and products. Here are some common applications of PIB:

1. Adhesives and Sealants: PIB is used as an adhesive or sealant due to its excellent tackiness, adhesion, and sealing properties. It can be found in products such as tapes, labels, and sealants for construction, automotive, and packaging applications.

2. Lubricants and Greases: PIB is used as a thickening agent in lubricants and greases to enhance their viscosity and improve their performance at high temperatures. It provides excellent film-forming and boundary lubrication properties.

3. Fuel and Oil Additives: PIB is used as an additive in fuels and lubricating oils to improve their viscosity index, reduce foam formation, and enhance lubricity. It helps in reducing wear and friction in engines and machinery.

4. Rubber Modification: PIB is utilized as a rubber modifier to improve the processability, flexibility, and elongation of rubber compounds. It is added to rubber formulations for applications such as tire inner liners, hoses, gaskets, and automotive parts.

5. Personal Care Products: PIB is used in personal care products such as cosmetics, lotions, and ointments as a thickening agent, emollient, and film-forming agent. It provides moisturizing properties and helps in enhancing the stability and texture of these products.

6. Packaging: PIB is used in packaging materials, such as films and coatings, to provide gas barrier properties, moisture resistance, and adhesion. It helps in extending the shelf life of packaged products by preventing gas permeation and moisture ingress.
