The material is capa- ble of achieving UL Oil Resistance I and II ratings, features an oxygen index of 41%, and, with a brittle point of -16 °C, is suited for indoor use. ● Apex ® 70020 is a 79 Shore A PVC compound for outdoor-rated jackets over crosslinked polyethylene. It is capa- ble of Oil I and II ratings and is designed to pass -25 °C cold impact and -40 °C cold bend tests. ● Apex P-55007 is an 82 Shore A blend of PVC and thermoplastic polyurethane (TPU) formulated for use in appliance wiring and tray cables over polyethylene cores. The most flame-retardant of a se- ries of PVC/TPU blends, it has an oxygen index of 35% and a brittle point of -49 °C. ● Flexalloy ® 9627-79 is a 67 Shore A PVC elastomer develo- ped as a spatter-, oil-, and UV- resistant material for welding cable. It meets the UL-62 stan- dard for flexible cable and is for use over PVC or crosslinked polyethylene cores. The low- gloss compound has a -38 °C brittle point and a 34% oxygen index.

Seeking to obtain better results and minimize the time it takes between testing and production, Guill built its own rheology lab in their facility in West Warwick, Rhode Island, USA. The lab n Guill Tool, manufacturers of extrusion tooling for the global market, has opened an in-house rheology laboratory, making it the only extrusion tooling ma- nufacturer in the industry with such a ca- In-House Rheology Lab launched features several key machines that en- sure optimum results, when testing ma- terials, especially new compounds to be extruded. The testing equipment in- cludes a Hybrid Rotational Rheometer, a Differential Scanning Calorimeter, and a Thermal Conductivity Meter. Third-party testing facilities are typically not experienced in extrusion processes. Guill, however, can not only gather data the same way third-party testers can, but can also interpret that data as it applies specifically to extrusion. Likewise, third- parties simply supply data, not recom- mendations. Guill is now equipped to both test its customer’s materials and work with them to create extrusion tool- ing that will give them a competitive edge. Accurate simulation and interpre- tation by extrusion experts greatly re- duces the number of physical reworks needed, as the tooling has a greater chance of producing a good product at the outset. In-house testing also speeds up the turn- around on test results, reducing delays New Guill Rheology Lab at company headquarters in West Warwick, Rhode Island
