Description

Introduction to Polybutenes :

Polybutene KVIS 10 is mainly used as lubricant for modifying / altering / improving the viscosity of the lubricant formulation to the required final viscosity. Polybutene KVIS 10 are used in those applications where there are plenty of chances for incidental contact of the lubricant with food such as production of aluminium foils and cans. Polybutene KVIS 10 are naturally very good lubricants and its distinctive physical properties make them a ideal choice for wide variety of lubrication applications. The vast range of viscosities of the Polybutene KVIS 10 render the operational comfort to the lubricant formulators. In other words the formulators would have a significant scope to design and optimize the formulations of the lubricants. Chemex Chemicals is one of the leading Importers and Suppliers of Polybutene KVIS 10 in India.

Advantages :

The typical benefits of Polybutene KVIS 10 over other Polyisobutylene is characteristics of very low deposit formation. It means, when it is heated over 2500 C they will depolymerise. The remarkable characteristics of KVIS PIB are very low toxicity and superior thickening capacity. Polybutene KVIS 10 bestows you with excellent shear stability. KVIS polybutenes are vastly applicable in Non staining metal working fluids, Extreme temperature / speciality lubricants, high viscous / energy effective gear oils and greases.

1 ) Asphalt modification

Polyisobutylene can be utilized to alter the Asphalt that can be used construction of roads. Adding polyisobutylene to asphalt gives give better flexibility in low temperature, better weathering and an outstanding aggregate/binder adhesion.

2) Adhesives

Hot Melt Adhesives & Pressure Sensitive Adhesives of different types make use of Polybutene KVIS 10 as a essential constituent.

Addition of Polyisobutylene assists in modification of properties like :

• Tackiness
• Increased Softness
• Enhanced Bond strength
• Cohesive strength
• Improves Water resistance of adhesives

It is better to use high molecular weight / viscous grades as a partial or total replacement for the expensive resins, which in turn also reduces the formulation costs.

Major Pressure-sensitive adhesives which can be made better with Polyisobutylene are as follows :

• Surgical tapes
• Industrial tapes
• Adhesives which are used for paper laminating, labels and tapes
• Masking and friction tapes

Natural & Synthetic Rubber’s tackiness can be improved by using Polybutene KVIS 10. Additionally, it assists in improving the quick sticking and peel strength of the elastomers.

Polybutene KVIS 10 attribute to various essential functions when it is blended into hot melt adhesives (HMA) such as :

• As an extender for Polymer
• Plasticiser
• Tackifier
• Wetting agent

Polybutene improves the cold temperature flexibility and drops the melt index.

Major applications of Polybutenes in these Hot Melt Adhesives include

• Manufacturing of Packaging Material
• Used for making Disposable soft goods
• Binding of Books
• Shoe Sole, Sealing of Carton and Furniture

The tackiness and adhesion property of the tie layer in multi-layer food packaging applications can be improved by using Polyisobutylene.

3) Rubber modification

Polybutene KVIS 10 are used as extenders and plasticizers for a wide variety of vulcanized elastomers like butyl rubber, natural rubber, PB, polyisoprene, SBR & ethylene-alpha olefin rubber.

It is not easy to extract Polybutene KVIS 10 from the elastomer by solvents as the mineral oil can be easily extracted using solvents. Also, polybutenes are impenetrable to exudation by heat ageing. Therefore, Polybutene KVIS 10 impart their properties permanently to the rubber.

It is possible to use the Polybutene KVIS 10 to plasticize the roofing and pipe wrap compounds made from butyl rubber or EPDM modified butyl rubber.

Properties of this compound are as follows :

• Colour / UV stability
• Outstanding tensile strength
• Elongation
• Low temperature adaptability

Furthermore, these polyisobutylene are also compatible with the elastomeric portion of thermoplastic block copolymers like butylene-ethylene-styrene block copolymer. polyisobutylene soften and plasticize such elastomers in low concentrations. Whereas at higher levels, polyisobutylene contribute in providing tackiness and adhesive properties.

4) Coatings

Polybutene KVIS 10 can be used as a functional component in numerous special purpose paints and coatings applications.

Benefits of using polybutenes in such applications are :

• Better Water resistance
• Improved Plasticization of the final film
• Low colour
• Outstanding Adhesion
• Easy replacement of volatile solvents

Manufacturing costs can be reduced by using Polyisobutylene emulsion formulations and addition of Polyisobutylene in the formulation improves water resistance as compared to the commercial acrylic-based systems.

Below are the coating applications in which KVIS Polybutenes can be utilized :

• Thermoplastic road marking paints (Hot applied)
• Masonry paints (as an non-hazardous alternative to chlorinated plasticizer)
• Waterproofing protection for wood & concrete

5) Polymer modification

Polybutene KVIS 10 is very much used in polymer alteration processes. Polypropylene random and impact copolymers modified with polybutenes has following properties

• High melt flow levels
• Higher elongation
• Better impact strengths.

KVIS Polybutene is used to wet the fillers and aid processing in filled and reinforced polypropylene.

Polyisobutylene can improve following attributes in polypropylene homopolymer film applications :

• Flexibility
• Makes it Tear resistant
• Improves Glossiness
• Better Clarity
• Polyisobutylene incorporation can improve tear strength by 100%.
• Thermoplastic resins – KVIS Polybutenes can increase
• The Impact strength
• Flexibility and
• Melt flow rate

Polyisobutylene help in improving the melt flow in crystal polystyrene. As compared to mineral oil while maintaining higher strength and heat deflection temperature, it gives better melt flow. Adding Polybutene KVIS 10 improves the environmental stress crack resistance (ESCR) of high impact polystyrene (HIPS) to fats & oils.

Addition of Polyisobutylene in the compound helps in increased izod impact strength of acrylonitrile-butadiene-sytrene (ABS) & also maintains heat deflection temperature and increasing melt flow rate.

Addition of KVIS Polyisobutylene in the compound helps in improving the impact strength of ethylene-propylene diene monomer (EPDM)/polypropylene compounds.

6) Personal care

These Polybutene KVIS 10 are pure, clear and basically non-toxic polymers. Lip Gloss & Roll On Deodorants are formulated with this polyisobutylene. Looking at the high purity of KVIS polybutenes, it can be used as a substitute for fatty esters and other expensive oils in the personal care product’s formulations.
