Rubber Durability Enhancement

A rubber manufacturer supplying automotive, industrial sealing, and cable protection applications was facing increasing customer demand for higher durability, longer service life, and more consistent product performance.

In automotive hoses and seals, premature aging and ozone cracking reduced service life.
In industrial rubber components, heat and chemical exposure caused performance instability.
In cable jackets and protective sheathing, weathering and UV degradation limited long-term reliability.

As order volumes increased, maintaining stable quality across large-scale production became a critical challenge.

Solution

Our Chlorosulfonated Polyethylene (CSM) was selected to upgrade the customer’s rubber formulations across multiple application lines. The material delivered:

• Outstanding heat, ozone, and weather resistance for automotive rubber parts

• Excellent chemical and aging stability for industrial sealing applications

• Superior flexibility and crack resistance for dynamic rubber components

• Long-term UV and environmental protection for cable jackets and protective sheathing

Its consistent quality also ensured reliable processing and reproducibility in high-volume manufacturing.

Implementation

Over a 6-week implementation period, we supported the customer with:

• Application-specific formulation optimization for automotive, sealing, and cable compounds

• Performance testing under simulated heat, ozone, and weathering conditions

• Trial production runs to validate processing stability and surface quality

• Technical guidance to ensure smooth integration into existing rubber production lines

Results

After one year of continuous production using our CSM:

• Automotive rubber components achieved significantly longer service life with improved aging resistance

• Industrial seals and gaskets showed enhanced stability and reduced failure rates

• Cable jackets and protective coverings demonstrated improved weatherability and long-term durability

• Overall product quality and consistency improved, enabling the customer to confidently meet growing market demand

• Increased customer satisfaction and repeat orders strengthened their competitive position across multiple sectors
