CAP’s wiper rubber is a key enabler of the latest technology
with competitiveness.

CAP is leading the way in developing technologies from NR wiper rubber production to silicon rubber development.
The blending techniques of high functional natural rubber and artificial rubber offer excellent durability, stable wash-off, and side-bearing.
Also, CAP enhanced the natural rubber’s low weatherproof ability through special skills.

Rubber Coating Part

Enhance the durability, wipe out, water repellency with a special coating on wiper’s rubber blade
Abrasion/close coupling/synovial layer/hydrophobic layer

Graphite Coating

Graphite: General

Maintain the capability of lubrication against wax contamination,
and minimize the noise and shivering while operating the wipers
Wipe-off/durability/shivering/protect water repellency/protect wax/noise

Water Repellent Coating

Graphite + Water Repellent Material: Specialized

The cohesive condition of synovial layer and hydrophobic layer
Secure the clear sight through the hydrophobic layer while operating the wiper blades in wet weather
Maintain the excellent hydrophobic quality and automated construction process through one-touch wiping
