Synsoly, as an OBP PP Products supplier and exporter, has specially developed high-end recycled new materials for global brands that attach great importance to marine ecological protection and ESG carbon reduction compliance. Through high-molecular physical modification, multi-level salt and sand purification, high-temperature top-space deodorization, and micrometer-level melt filtration technology, we transformed it into high-quality modified resins with physical properties extremely close to the original PP. This solved the problems of equipment corrosion caused by high salt content in coastal waste, severe degradation of molecular chains due to long-term exposure of waste, and the risk of greenwashing due to opaque source certificates.

1. We have an engineering team that has been deeply engaged in the field of physical modification of plastic recycling along the coast for many years. They have precisely mastered the pre-treatment and polymer reconstruction rules for waste materials degraded by high salt, high sand, and strong ultraviolet radiation along the coast.
2. The factory testing center is equipped with spectrophotometers, high-precision melt index testers (MFR), simply supported beam impact testing machines, ash content testers and DSC thermal analyzers, strictly monitoring the purity and mechanical properties of each batch of OBP resin.
3. Our OBP PP Products cover the GRS Scope Certificate and pass the REACH 2.0, RoHS, PAHs and Food-contact Food Contact safety screenings of international institutions such as SGS and TUV.
4. From the factory packaging diagram of raw materials, the photos of the modification and granulation production line in the factory, the actual photos of the shipping containers, and the third-party test reports, the entire process is kept transparent and open.
OBP-PP-INJ100 series: General injection molding grade, suitable for marine environmental protection theme home storage, stationery shells and daily necessities.
OBP-PP-HI200 series: High impact resistance modified grade, specifically used for consumer electronics packaging inner linings with high drop test requirements and toolbox bodies.
OBP-PP-UV300 series: High weather resistance bathroom grade, with added anti-ultraviolet and anti-saponification additives, suitable for the same shower head pressing components of Nine-Mu.
OBP-PP-BM400 series: Hollow blow molding grade, used for shampoo bottles, shower gel bottles and daily chemical packaging containers.
Compared with ordinary PCR (post-consumer recycled plastic), OBP has a social public welfare attribute, higher traceability requirements, and can provide stronger environmental protection story endorsement for brands.
No. Synsoly has added a proprietary multi-stage desalination and powerful washing system in the pretreatment stage, reducing the trace salt and sand particles inside the material to an extremely low level, which will not cause corrosion to your injection molding screws or molds at all.
Yes. All products undergo regular inspections by SGS to ensure compliance with the EU REACH (SVHC high-concern substances screening), RoHS, and PAHs environmental regulations. This enables them to smoothly enter the demanding markets of Europe, North America, and Japan.
