Morken Industrial Granted Invention Patent for Butyl Rubber to Boost Domestic Substitution
On February 6, 2026, Moken (Xiamen) Industrial Co., Ltd. was granted an invention patent for “A Butyl Rubber and Its Preparation Method” by China National Intellectual Property Administration (CNIPA), Patent No. ZL 2025 1 1728073.7.
Filed on November 24, 2025, the patent was approved in just over two months, reflecting its strong novelty and inventiveness under strict substantive examination.
Butyl rubber is widely used for its excellent air tightness and moisture barrier. However, traditional grades face limitations in flowability, compatibility and vulcanization control. With higher demands from new energy, medical and construction industries, innovative upgrades have become essential.
Our patented technology focuses on composite vulcanization system, filler modification and precise mixing process, with dual protection on formula and preparation method. It significantly improves batch stability, processing consistency and long-term reliability for end users.
As a professional manufacturer based in Xiamen Tong’an, Moken specializes in rubber sealing products and custom compound rubber. The patent is developed by our core R&D team and supported by pilot verification, ensuring real industrial application.
The technology will be mainly applied in new energy power battery sealing and medical stoppers & infusion components, with future expansion to consumer electronics and building airtight materials.
As the world’s largest butyl rubber market, China relies heavily on imports for high-end modified grades. This patent helps break foreign IP barriers and promotes domestic substitution with independent intellectual property.
Moken will continue to drive innovation and industrialization, providing reliable, high-performance sealing solutions for global customers.
