Low-temperature validation
Real-world road validation in extreme cold
To address potential embrittlement, phase separation, and detachment of self-sealing and bonding materials in extreme cold, Lange Jiach continuously validates products in different environmental conditions.
At the end of 2025, the company's products underwent real-world road testing in Mohe, Heilongjiang, where the lowest ambient temperature reached approximately -42℃.
During the road test, no obvious signs of the following were observed:
- abnormal crystallisation
- material embrittlement
- phase separation
- adhesive backing detachment
- material bonding failure
This provides a further validation basis for real-world use in cold regions.
From the laboratory to the road, we focus on the long-term performance of materials on real tyres, real roads, and in real environments.

Self-sealing material technology
Balancing flow and stability
Self-sealing materials are not simply about pursuing greater strength or hardness. Effective materials balance:
structural stabilityandmaterial flow
Materials need sufficient structural stability to prevent uncontrolled flow in long-term use, while retaining suitable viscoelasticity and deformation capacity to respond quickly after puncture, vibration, or dynamic impact.
SILENT ZONE conducts systematic research into material viscoelasticity, rheology, interfacial bonding, structural stability, and temperature adaptability. Balancing these dimensions helps materials better suit the tyre's complex dynamic operating environment.

Flexible self-sealing bonding technology
More than bonding: adapting to long-term tyre deformation
In real operation, tyres continuously experience vibration, impact, bending, temperature changes, and dynamic deformation. Traditional rigid bonding systems can create local stress concentrations under long-term dynamic loading.
SILENT ZONE flexible self-sealing bonding technology uses a material's viscoelasticity and deformation adaptability to form a flexible connection between acoustic foam and the tyre inner liner. The material can deform with the tyre to reduce interfacial stress concentration in long-term use.
We focus not only on initial bonding strength, but on the balance between: long-term bonding + dynamic deformation + temperature change + durability.

Research and technology development
Continuing to explore new possibilities for tyre functional materials
Lange Jiach continues research and development in tyre noise reduction, self-sealing, and functional materials, with an R&D process spanning material characterisation, system design, processing, and end-use evaluation.
The company works with Otsuka Material Technology on relevant materials technology, continuing technical exploration in functional material systems, material-performance research, and application evaluation.
- Materials technology
- Research into the viscoelasticity, rheology, interfacial bonding, and long-term stability of polymer materials.
- Process technology
- Continually optimising compounding, extrusion, forming, lamination, and application processes to improve processing stability and product consistency.
- Application technology
- Evaluating material performance under temperature, vibration, deformation, and long-term use conditions in the tyre's real operating environment.
- Product iteration
- Continually improving products based on real application feedback, so material performance better matches differing tyre application needs.

Research philosophy
Materials are not isolated; application is the ultimate standard
Between laboratory performance and real road use lie complex material, process, and environmental variables.
We therefore focus not only on laboratory data, but also on what happens after materials go through:
- processing
- forming
- application
- tyre assembly
- real-world operation
their final performance. By continuously accumulating material, process, and application data, we move products from laboratory research toward standardised, scalable application.
