TECHNICAL DATA SHEET
Product Name: Norst® PB-402-24
Norst® PB-403-34
Norst® PB-404-44
Product Description
Norst® PB-402-24: Is a highly modified polybutylene polymer that exhibits high tack and cold flow over a very wide temperature range (-70°F to 450°F, with variants stable to 650°F and 800°F). It is impermeable to water or oxygen. It has good tensile and bond strength, high film strength, permanent tackiness, excellent aging/weather resistance, low stain, low electrical conductivity. It is odorless, colorless, and highly stable. Chemical resistance is comparable to other polyisobutylene polymers. PB-402-24 can be used as a high performance additive in any non-aqueous system where high tack and elasticity are needed.
Typical Properties
Uses
Adhesives: High tack and elasticity in PSA adhesives; water and gas proof barrier in sealing tapes; cold flow properties make it ideal for use in “self-healing” barrier products. Variants functional at very high temperatures, Norst® PB-403-34 up to 650F ( 343C), Norst® PB-404-44 up to 800F (427C).
Sealants: Waterproof and gas proof barrier; excellent tack and elasticity for sealants and mastics; cold flow over a wide temperature range in “self-healing” products; good internal cohesive strength.
Products
Industrial and nonwoven adhesives, barrier tapes, electrical insulation and cable filler, construction mastics and caulks, window and door sealants, waterproofing compounds, pipeline protection, roofing membranes, bitumen modification, etc.
Substrates and Systems – Chemistry Non-Polar
Core structure: Distinctly branched aliphatic which gives excellent chemical, weather and oxidation resistance, stability and low color. Best functioning in butyls, EPM/EPDM, microcrystalline wax, asphalt and, polypropylene, HDPE, LDPE, polyisobutylene, etc.
Diluents and carriers: Aliphatic and napthenic solvents work very well.
Suitable for solvent-based composition hot melt adhesive and sealant applications, and can be formulated with other polymers, resins, filters, pigments, oils, thickeners, waxes and stabilizers to obtain a desired balance of properties. Avoid strong oxidizers.
NorthStar Elastomers provides broad product modification opportunities through blending of custom polymers to modify tack, elasticity, temperature stability, etc.
Polar polymers: (Such as urethanes, acrylics, polyesters and polyamides) are generally incompatible. Avoid polar solvents.
Packaging
45 pound Quick Relaese boxes; 350 pound Quick Release, open head drums.
