SI Group Polymer Modifiers are the industry's leading compatibilizers, which are also known as functionalized polymers, coupling agents or impact modifiers. They are used in applications such as PVC calendaring, PVC profiles, engineering thermoplastics compounding, thermoplastic elastomers, epoxy adhesives and coatings, masterbatches, polyolefin compounding, filler coupling, solvent adhesives, and alloy compatibilization.
Difficulties dispersion of polar fillers in non-polar polypropylene resins Poor adhesion of fillers to the polypropylene matrix High moisture absorption in polyolefin products and resins Creep and low flexural strength in thermoplastic products and formulations Low impact resistance and cracking issues in polyolefins and engineered resins Long lead time and supply issues of polyolefin compatibilizers and coupling agents
PB 3349 allows for high load rates of HFFR without sacrificing tensile strength, tensile modulus and elongation properties of your compounds.
The POLYBOND™ 3200 from SI Group is legendary for its performance as a coupling agent in plastic applications. The 3200 outperforms other coupling agents with superior thermal stability, color control and less degradation.
