Polyether L-63's environmental attributes are specified in the safety data sheet of Hai'an Guoli Chemical Co., Ltd. According to the EU CLP Regulation (EC) No. 1272/2008 and China's GB 30000 series standards, this product is classified as a non-hazardous substance with no GHS hazard category, no pictogram, and no signal word. Its ecotoxicological data indicate that the product is environmentally friendly and does not belong to persistent, bioaccumulative, or toxic (PBT) substances, nor to very persistent, very bioaccumulative (vPvB) substances.
Regarding biodegradability, polyether L-63 has been tested according to OECD 301F, with a degradation rate greater than 60% ThOD, falling into the "readily biodegradable" category. This means that after entering the environment, the product can be rapidly broken down by microorganisms and will not persist in the ecosystem for a long time. Additionally, its acute toxicity to aquatic organisms (fish, algae, daphnia) has an LL50 value greater than 100 mg/L, which is classified as low toxicity to aquatic organisms.
The product has a high flash point (closed cup flash point greater than 200°C), is a non-flammable liquid, does not form explosive vapor/air mixtures, and poses low environmental safety risks during use and storage. Overall, polyether L-63 fully meets the basic requirements of current domestic and international environmental regulations under normal use conditions.

Due to its excellent environmental properties, polyether L-63 is particularly suitable for industries with high requirements for green and environmental protection. In the production of end-consumer goods such as automotive interiors (seat foam, steering wheels, armrests, etc.), furniture industry (high-resilience cushioning materials), and shoe materials (microporous elastomers for soles and insoles), using polyether L-63 helps meet international environmental certification requirements such as REACH and OEKO-TEX standards. Choosing this product in polyurethane adhesive and coating formulations also helps reduce VOC emissions and overall environmental footprint of the final product.
The product quality inspection documents that Hai'an Guoli Chemical Co., Ltd. can provide typically include the Certificate of Analysis (COA), covering physical and chemical indicators such as hydroxyl value, acid value, moisture, and pH value. For third-party environmental certification documents such as ROHS test reports, REACH compliance declarations, and SGS test reports, as well as the MSDS/SDS safety data sheet, it is recommended to contact Guoli Chemical's sales or technical department directly to obtain the latest versions. Test reports for different batches may vary; please refer to the officially stamped documents.
To obtain the above documents, you can visit the official website of Guoli Chemical or call customer service. When requesting, please specify the required report type and product batch number so that the staff can quickly retrieve the corresponding test data for you.
