Everything buyers ask before ordering custom polyurethane foam
We manufacture polymer polyurethane foam. Our range covers reticulated filter foam from PPI 10 to PPI 100, bio-carrier foam for water treatment, activated carbon foam, flame-retardant foam tested to UL94, photocatalyst foam, melamine cleaning sponges and memory foam for home textiles - more than 20 foam grades in total.
Our plant is in Pingdi Street, Longgang District, Shenzhen, Guangdong, China. Shenzhen sits in the Pearl River Delta manufacturing belt, which gives our customers fast access to Hong Kong and Guangzhou ports for export shipping.
Yes. OEM and ODM orders are our core business. Send us a drawing, a sample or simply the target dimensions and performance requirements, and we will recommend density, pore count (PPI), hardness, thickness and the right converting method - die cutting, CNC contour cutting, lamination or reticulation.
For filter foam you can specify pore count (commonly PPI 10, 15, 20, 30, 45, 60 and above), density (kg/m3), thickness, colour, whether the structure should be reticulated (open-cell blast foam) and whether you need additives such as activated carbon, photocatalyst or flame retardant.
Our flame-retardant grades meet the UL94 standard and are used in automotive sealing, sound insulation and electronics packaging. Tell us your target rating and we will match or develop a formulation for it.
We are ISO 9001 certified and recognised as a National High-Tech Enterprise in China. Products can be supplied with FDA, SGS and sterilisation test reports for the relevant grades.
Environmental treatment (water filtration, microbial bio-carriers), industrial applications (precision instrument filtration and protective packaging), automotive (sealing, sound insulation, flame-retardant parts), household cleaning, home textiles and bedding, toys, cosmetics and product packaging.
