AI Technical Summary
The chlorinated butyl rubber currently used in tire inner linings suffers from problems such as slow vulcanization speed, poor processing performance, high cost, and environmental impact, making it difficult to meet the requirements for lightweighting and environmental protection.
The combination of a rubber composite layer and a plastic resin layer utilizes the low-density properties of thermoplastic resin to reduce rolling resistance by decreasing the width and thickness of the tire, and employs renewable rubber materials to achieve lightweighting and environmental friendliness.
This achieves tire weight reduction, lower rolling resistance, improved fuel efficiency and dynamic performance, while reducing environmental impact and optimizing tire air tightness and safety.
