Thermal Processing & Manufacturing Capabilities
Zhejiang Geruite Packaging Materials Co., Ltd. manufactures high-temperature tapes equipped with silicone and acrylic formulations designed for high-heat environments. Precision calendering and cross-linking thermal curing processes ensure structural unity between carrier backings and adhesive layers.
Every production batch undergoes thermal exposure testing in forced-air ovens to confirm dimension retention, dielectric breakdown resistance, and post-bake clean-removal properties.
Target Application Fields
- Powder Coating & E-Coating Masking: Protects threaded holes, contact points, and mating surfaces during high-temperature bake cycles up to 200°C.
- Printed Circuit Board (PCB) Wave Soldering: Shields gold fingers and sensitive contacts from molten solder pots at 260°C.
- Transformer & Motor Insulation: Functions as Class H and Class F electrical insulation wrapping for copper coils and wiring.
- Automotive Engine Bay Harnessing: Bundles cables and protects sensor lines located near elevated heat sources.
