In plastics applications InChemRez® Phenoxy resins offer a wide selection for your chosen technology. Phenoxy resins find use in blends of PBT, PET, PPO, nylon, and polycarbonate resins for modifying physical properties such as tensile, flexural, and impact strengths. The addition of Phenoxy improves pigment/filler wetting for appearance and rheology control. Additionally Phenoxy resins are useful as compatibilizing agents for dissimilar plastics like polyolefins and polyesters.
 

Because of transesterification reactions Phenoxy resin can behave as processing aids with polyesters such as polyethylene terephthalate during extrusion.

Plastics Selection Guide

Because of its unique structure and properties Phenoxy resins, when used as additives in plastics applications, can greatly improve not only the processability of these materials but also improve the quality and performance of the finished product.

During processing the addition of Phenoxy can help to control process rheology as well as the heat distortion temperatures in extrusion, molding and film formation operations. The amorphous nature of Phenoxy resin can also be helpful in controlling the crystallization kinetics of thermoplastic materials.

Alloys made with Phenoxy have been shown to possess improved thermal stability.  The toughness of Phenoxy resins also imparts improved mechanical performance to finished products.  As a result, the addition of Phenoxy resins can result in cost reductions as less material (thinner cross sections) is required to achieve the desired performance. The excellect vapor barrier properties of Phenoxy resins can be beneficial in plastic film applications where protection against moisture or oxygen is required.
