The latest addition to the HYTAC® portfolio of syntactic foam plug-assist materials for the thermoforming industry is being launched by CMT Materials, and is said to be well suited for “sticky” materials and a range of other high-performance applications.
Available in a variety of sheet and rod sizes, HYTAC® HTF is the latest in toughened copolymers that are easy to use and extend the performance range to fill challenging market needs, according to John Moy, HYTAC® sales and marketing manager. The company has witnessed strong growth for HYTAC® HTF and is the culmination of collaborative work with leading thermoforming companies to optimize plug-assist material choices.
HYTAC® HTF syntactic foam is capable of high service temperature performance (232°C/450°F) based on a toughened copolymer formulation and microsphere size which is the smallest CMT Materials has ever used. It is said to enable lower heat transfer between the plug and sheet. The plug-assist material promotes evenly distributed material throughout the entire part and is excellent for deep-draw applications due to its high friction. It is easily polished to a mirror-like surface while maintaining optimal friction properties, making it an ideal choice for use with sticky barrier films to minimize plug buildup.
In barrier applications, HYTAC® HTF has been shown to reduce additive buildup and cleans quicker, thus reducing downtime and labor cost. The material’s small microsphere size facilitates the production of highly transparent and clear parts. Moreover, such copolymer plug materials also provide dust-free machining and high strength. Its durability makes it highly effective in pushing the film into smaller corners and other troublesome areas.
CMT Materials will be exhibiting new technology at NPE 2024 in Orlando, FL this May, at booth W6888.
