Foire aux questions
What is high-strength PP board made of? Answer : High-strength PP board is manufactured from premium polypropylene resins, including up to 50% recycled PP that meets the Global Recycling Standard (GRS) . The recycled content is carefully sorted and processed to maintain consistent mechanical properties — tensile strength, impact resistance, and thermal stability — equal to virgin-grade PP boards. This makes it an ideal choice for buyers seeking both performance and sustainability compliance.
What does “dual-hardness design” mean in PP board? Answer : Dual-hardness refers to PPBOXY’s proprietary manufacturing process that creates PP boards with two distinct hardness zones within a single sheet. The surface layer offers higher rigidity for structural support, while the core maintains flexibility for impact absorption. This dual characteristic is particularly valuable in automotive interior panels (where surface stiffness meets crash-energy absorption) and footwear midsoles (where firm support meets cushioning comfort). Most standard PP boards on the market do not offer this capability.
Is this PP board GRS certified? Answer : Yes. PPBOXY’s high-strength PP board is manufactured using up to 50% recycled PP resins and is certified to the Global Recycling Standard (GRS) . The GRS certification verifies the recycled content percentage, chain-of-custody documentation, social and environmental practices, and chemical restrictions. This certification is increasingly required by European automotive OEMs , medical device manufacturers, and consumer brands with corporate sustainability mandates. A Certificate of Conformance (CoC) is available upon request for each production batch.

Is high-strength PP board suitable for shoe manufacturing? Answer : Yes — this is one of the fastest-growing applications. PP board’s dual-hardness design is ideal for footwear components:
Midsoles : The flexible core absorbs walking impact while the rigid surface maintains shoe structureOutsoles : Excellent abrasion resistance and gripHeel counters : High-strength surface layer provides rear-foot stabilityInsoles : Lightweight, moisture-resistant, and anti-odor (PP is naturally antimicrobial)
Compared to traditional EVA and PU midsole materials, PP board offers 30–50% weight reduction with superior structural integrity. It is fully recyclable, which aligns with growing sustainability requirements from global footwear brands.
What is the minimum order quantity (MOQ)? We don’t believe in a one-size-fits-all MOQ. Whether it’s a single sample or a bulk production run, we’re happy to work with whatever quantity you have in mind.
