The resulting custom-formulated grades of GLS™ Dynalloy™ OBC and Versaflex™ TPE allowed the manufacturer to switch to a two-shot molding process that eliminated the time-consuming and costly assembly operations needed for the old part. Reduced assembly costs: Switching to Dynalloy™ OBC and Versaflex™ TPE allowed the introduction of two-shot molding, which eliminated a multi-component assembly process.

A variety of base resins can be used to create Surround formulations to either concentrate (intended to let down at the press) or direct-to-mold fiber loadings.  Design freedom of injection molding, including thinner walls

Additional benefits of the material include a UL Yellow Card V-0 flammability rating, pre-colored capabilities for simplified molding, and a wider processing window to help accommodate a variety of molding environments.

Cesa Withstand additives include organic and inorganic ingredients to inhibit the growth of bacteria, mold, and fungi on the plastic surface, providing uncompromising antimicrobial performance. The two new available grades of Cesa Withstand for TPU film can meet the specific anti-bacterial and anti-mold protection needs of medical beds, transparent tent components, and ice bags.

OnColor™ color and additive concentrates help manufacturers transition away from paint to in-mold color (IMC) solutions that maintain aesthetic qualities while eliminating production steps.   Efficient slush molding: Recently introduced low-temperature Geon™ VBX vinyl powder formulations for automotive interior surfaces and instrument panels meet OEM low temperature requirements and can provide production efficiency improvements of 15% or more.

PolyOne supported the design and production engineers at Sylumis with thermal simulation and mold filling analysis to help the manufacturer optimize the geometry, heat transfer and manufacturability of the heat sinks. The specialty polymer solution from PolyOne meets relevant safety standards, including a UL94-V0 flame class rating at 3mm thickness, and offers Sylumis significant production efficiencies via injection molding in place of metal forming.

Working with PolyOne to transition from metal to plastic helped Resol increase its design options, lower overall weight and reduce manufacturing complexity, PolyOne was also able to help Resol achieve excellent aesthetics with molded-in color while eliminating the cost and hassles of painting. Based in Girona, Spain, the Resol furniture company includes Resinas Olot, a leading global manufacturer of plastic furniture for outdoor, office and residential use, and Plasfur by Resol, which offers injection molding and manufacturing services to customers in various industries.

An advancing core should be used when the mold opens and the elastomer should be allowed to deflect as it is ejected. Most GLS styrenic TPEs (Dynaflex and some Versaflex) have fairly high mold shrinkage and cause the overmolding TPE to contract more than the substrate, which can result in warpage or cupping of the substrate part.

This can occur due to improper injection molding conditions or the incompatibility of a TPE or vulcanized silicone material with certain additives. In addition, the materials’ outstanding mold release improves cycle times, reducing overall energy use to support manufacturers in reaching their sustainability goals.
