Top 4 PU Stone Manufacturers in China

Haining Yike New Materials Co., Ltd.

Lightweight and high strength: Using polyurethane resin as the core raw material, the product has low density (usually 30-80kg/m³), and its weight is only 1/5-1/3 of that of natural stone, which can greatly reduce the installation load-bearing requirements; at the same time, through formula optimization, the tensile strength can reach more than 10MPa, and the impact resistance is better than traditional artificial stone.

Weather resistance and durability: After special process treatment, the product has UV aging resistance of more than 5,000 hours (equivalent to no obvious fading outdoors for 5 years), and the physical properties are stable under -40℃ to 80℃ environment, not easy to crack or deform, suitable for scenes with high humidity (such as bathrooms) and strong ultraviolet rays (such as exterior walls).

Environmental protection and safety features

Low VOC and formaldehyde-free: The production process adopts water-based foaming process, and the emission of volatile organic compounds (VOC) is ≤1mg/m³, which complies with the EU CE certification and domestic GB 18583-2008 standards, and can be directly used in sensitive areas such as indoor children's rooms and bedrooms.

Flame retardant and anti-slip: By adding halogen-free flame retardants, the product flame retardant grade reaches B1 (flame-retardant material), and the oxygen index is ≥30; after the surface is frosted or litchi surface treated, the anti-slip coefficient (COF) is ≥0.6, which is better than natural marble (usually 0.4-0.5).

Application scenarios and customization capabilities

Multi-field adaptability

Architectural decoration: The simulation degree is more than 95%, which can simulate the textures of marble, granite, cultural stone, etc., suitable for villa exterior walls, commercial complex door heads, hotel background walls, etc.; supports dry construction (direct gluing or snap-on installation), and the installation efficiency is 3 times higher than that of natural stone.

Special scenarios: Excellent waterproof performance (water absorption rate <0.5%), can be used around swimming pools and hot spring resorts; the sound insulation coefficient is 30dB, which can be used as sound insulation wall panels in KTV, cinemas and other places.

Flexible customization service

Size and texture customization: large plates with a maximum size of 3000×1200mm and a minimum thickness of 5mm can be produced. Customers are supported to provide samples for mold opening (mold fees can be refunded), and the texture restoration error is ≤0.1mm36.

Fast color matching: The color paste integrated infusion process is adopted, and the color number covers more than 90% of the Pantone color card. Conventional colors can be sampled within 48 hours, and the batch production cycle is ≤7 days.

Cost and supply chain advantages

Lower overall cost

Production end: The automated production line (foaming-molding-cutting integration) is adopted, and the raw material utilization rate reaches 92% (traditional process is about 75%), and the unit production cost is 40%-60% lower than that of natural stone.

Construction end: No heavy lifting equipment is required, and a 2-person team of 100㎡ wall can complete the installation in 1 day, saving more than 50 yuan/㎡ in comprehensive construction costs.

Quick supply chain response

Raw material guarantee: Signed an annual agreement with suppliers such as Wanhua Chemical and BASF, with a polyurethane resin inventory of ≥300 tons, ensuring that the order delivery cycle is stable within 15 days (the industry average is 25 days).

Logistics coverage: Warehousing centers are set up in the Yangtze River Delta and the Pearl River Delta, supporting 24-hour delivery within 300km, 48-hour direct delivery across the country, and export products are declared through Ningbo Port, and the shipping cycle is 3-5 days faster than peers.
