| The use of syntactic materials as plug assist tooling replacing conventional materials such as aluminum, wood, felt or Delrin has become increasingly popular in the thermoforming industry. Syntactics, the combination of hollow glass spheres in a polymer matrix, have many unique properties that make them ideal candidates for both roll-fed and sheet-fed applications. Low Thermal Conductivity and Specific Heat: This translates to lower heat transfer reducing warm-up time and virtually eliminating material sticking to the plug. Dimensionally Stable: The low coefficient of thermal expansion means the plug maintains its shape over a wide temperature range. Excellent Temperature Resistance: HYTAC-W is specially formulated with an epoxy resin which maintains a high modulus at elevated temperatures. Lightweight: This increases the life of capital equipment due to reduced wear and tear on moving parts. Easily Machined: HYTAC-W can be easily machined to any size or shape using conventional equipment. Variety of Shapes and Sizes:The material is provided in standard sized rots or sheets, but may be custom molded to meet the specific needs. Applications: HYTAC-W is often used for short run or price sensitive applications, providing cost effective, low thermal conductivity plugs for quick start up times, better material distribution, improved surface appearance and longer life than basic alternatives. Recommended for use with PE, PS and PVC. Information Provided by CMT Materials, Inc. |
