EVA/PE Car Wash Brush
Specialized Foam Materials for Automatic Car Wash Brush Systems
EVA+PE Foam Materials Developed for Automatic Car Wash Systems
EVA+PE foam is widely used in automatic car wash systems, including tunnel, rollover/in-bay, and other types of automatic washing equipment. Car wash brushes must be soft and flexible to help minimize abrasion to vehicle paint surfaces. At the same time, they must withstand continuous rotation, stretching, bending, friction, and exposure to environmental factors such as water, detergents, and ultraviolet (UV) radiation.
As a result, the performance requirements for car wash brush materials are much more demanding than those for general-purpose foam products. We also offer a range of hardness options to accommodate different vehicle body types and application areas, helping achieve optimal cleaning performance.
Why Is EVA+PE Foam Suitable for Car Wash Brushes?
- Gentle Contact: The brush strips are soft and flexible. With water lubrication and appropriate contact pressure, they provide gentler contact with vehicle surfaces.
- Tear Resistance: The brush strips are less likely to tear when rotating at high speeds and undergoing repeated bending.
- Flexibility and Elongation: Designed to accommodate rotation, stretching, and the contours of vehicle bodies.
- Water Resistance: The closed-cell foam structure provides water resistance. Antimicrobial agents (such as silver ions) can also be added.
- Chemical Resistance: The material formulation can be adjusted according to the detergents used in car washes and the operating environment.
- Weather Resistance: A UV-resistant formulation can be added to withstand prolonged outdoor exposure.
- Reduced Dirt and Grit Retention: The closed-cell, water-resistant structure helps reduce the retention of sand and dirt on brush strips, lowering the risk of trapped particles scratching vehicle surfaces.

PHINOMENAL Development Capabilities
Phinomenal Co., Ltd. offers more than standard EVA foam. We provide development support for car wash brush applications, starting with material formulation and extending through product development. Based on each customer’s equipment and product requirements, we work from material selection and formulation adjustments to foam production and subsequent processing.
We understand that different car wash systems have different requirements for brush materials. Rather than using one standard grade of EVA foam for every application, we design materials based on equipment conditions and product requirements, working with customers to develop dedicated foam materials suited to their specific car wash systems.
