Product Characteristics and Materials

EVA is a closed-cell polymer foam material. Its characteristics are determined by the vinyl acetate (VA) content and foaming process:

• Lightweight cushioning: Wide density range (0.03-0.25g/cm³), lightweight, with good shock absorption and resilience.

• Stable physical properties: Non-toxic and odorless, corrosion-resistant, resistant to seawater and oils, and maintains flexibility even at low temperatures (-40℃).

• Excellent processing performance: Easy to perform secondary processing such as thermal lamination, cutting, and molding; the surface can be flocked or laminated with other fabrics.

• Economical and practical: High cost-performance ratio, a common choice for automotive floor mat substrates.

Product Uses and Application Scenarios

1.Main Uses: Primarily used as the middle cushioning layer and supporting base material for car floor mats, often combined with surface fabrics (such as Teslin or leather) and bottom anti-slip materials.

2.Core Application Scenarios:

• Original equipment manufacturer (OEM) floor mats for mid-range car models: Provides basic cushioning and protection.

• Base material for aftermarket full-coverage and semi-coverage floor mats: Widely used due to its good processability and cost advantages.

• Consumers who value practicality and cost-effectiveness.

Production Process

The process employs either compression molding or continuous foaming:

1. Mixing: EVA granules, foaming agent, crosslinking agent, color masterbatch, etc., are mixed evenly according to the formula.

2. Molding and Foaming: The mixture is placed in a mold and foamed under high temperature and pressure to form a stable closed-cell structure.

3. Curing and Setting: After foaming, the mixture needs to be left to cure and stabilize its dimensions and performance.

4. Post-processing: Cutting, laminating, punching, or surface treatment is performed as needed.

Quality Control

1. Raw Material Inspection: Batch testing is conducted on key raw materials such as EVA resin and foaming agent.

2. Process Control: Foaming temperature, pressure, and time are strictly controlled to ensure uniform density and cell structure.

3. Finished Product Inspection: Thickness, density, hardness, dimensional stability, and appearance (no cracks, shrinkage cavities, or other defects) are inspected.

4. Environmental Testing: Materials are ensured to meet environmental protection requirements and have no irritating odor.

Packaging, Transportation, and Shipping

1. Packaging: Rolls are wrapped in stretch film, and cut pieces are sealed in plastic bags and then placed in cartons to prevent moisture and deformation.

2. Transportation: Primarily by land transport. Pay attention to rain and moisture protection, and avoid direct sunlight.

3. Shipping: Regular products are in stock and can be shipped quickly; customized products have a production cycle of approximately 5-10 working days.

FAQ

1. Q: How durable is EVA as the base material for car floor mats?

A: Medium- and high-density EVA has good resistance to compression deformation and a long lifespan under normal use. However, irreversible indentations may occur under long-term heavy pressure.

2. Q: Are EVA floor mats waterproof?

A: EVA itself does not absorb water. However, when used as a base material, water may seep in from the edges if the seams of the surface fabric are not properly treated. Fully sealed edge bonding can effectively improve overall waterproofing.

3. Q: Why do some EVA floor mats have a strong odor?

A: The odor mainly comes from inferior foaming agents or recycled materials. We use environmentally friendly formulas and virgin materials, resulting in products with low odor that meet in-car usage standards.

4. Q: Can you make fully enclosed 3D floor mats?

A: Yes. EVA substrate can be hot-pressed and molded with surface and base materials to create fully enclosed 3D foot pads. However, the molding precision and durability of 3D edge-sealing are generally not as good as TPE injection-molded products.

5. Q: How to clean and maintain?

A: The finished foot pads can be wiped with a damp cloth. Avoid prolonged exposure to sunlight to prevent accelerated material aging.
