This is an important verification of the quality of our products and a reflection of our consistent pursuit of excellent quality.

Dear customers and partners:
Sealone Seals sincerely announces that our NBR material has successfully passed the PFAS test conducted by SGS (Swiss General Service). This is an important verification of the quality of our products and a reflection of our consistent pursuit of excellent quality.

PFAS (perfluorinated compounds) are a class of organic chemicals widely present in the Earth’s environment, possessing excellent properties such as water resistance, oil resistance, and heat resistance. However, due to its accumulation in the environment and potential ecological toxicity, PFAS has attracted widespread global attention and become a hot topic in the field of environmental protection in recent years. SGS is an internationally renowned independent third-party testing and certification agency, and its PFAS testing is recognized as one of the authoritative tests in the industry.

Our NBR material has passed SGS’s strict testing process for PFAS this time, and the results show that our product does not contain any PFAS substances and meets the requirements of relevant regulations and standards. This result is not only a strong proof of the high-quality performance of our materials, but also our confidence and responsibility to our customers and partners.


This milestone marks our company’s continuous innovation in the field of materials and efforts to continuously improve product quality. We have always been committed to meeting the needs of the market and customers, and continuously expanding and improving our product line. Through strict control and optimization of materials, we ensure excellent performance and environmental friendliness of our products.

We will continue to adhere to the business philosophy of “quality as the cornerstone and customer centered”, providing customers with higher quality and more reliable material products. In the future, we will continue to promote research and innovation, strengthen cooperation with domestic and foreign testing institutions, and strive to create more environmentally friendly and safe materials, creating greater value for customers.


Thank you again to all the customers and partners who have always supported and followed us. Let’s move towards a better future together
