APPLICATIONS
Product Applications
SG-8 represents a high-flow/food-contact grade resin. Its very low degree of polymerization ensures unparalleled mold-filling capability and processing efficiency, even in complex molds. Furthermore, its adherence to stringent hygiene and safety standards makes it the material of choice for food and pharmaceutical packaging, medical devices, high-clarity rigid containers, and thin-wall injection-molded parts.
