High-quality raw materials, 100% natural rubber

Shanghai Songjiang Vibration Absorber  Co., Ltd. official website introduces: Rubber Expanion Joint Raw Materials. Songjiang Group promises that all rubber expansion joints are made of high-quality raw materials, 100% natural rubber, without any recycled rubber. In case of counterfeit products, we offer a tenfold compensation. Songjiang Group has always pursued high-quality products to serve customers. High-quality products are inseparable from high-quality raw materials. Therefore, our factory has its own strict procurement standards for raw materials.

Furthermore, our company implements stringent procedures for selecting and utilizing raw materials. We conduct thorough inspections and assessments of potential suppliers to ensure their compliance with our quality standards. Additionally, our quality control team meticulously monitors the entire production process, from raw material procurement to finished product assembly, to guarantee that only the highest quality materials are used in our rubber joints. This commitment to excellence in material selection and usage reflects our dedication to delivering reliable and durable products to our customers.

If your project is a major engineering undertaking, I strongly recommend visiting the source factories in person. By doing so, you can inspect the standards of the raw materials and gain insight into the quality control measures employed by the factories. Otherwise, the consequences of a rubber expansion joint failure, such as flooding the entire pump room, could outweigh the benefits.

As the saying goes, real gold fears no fire. We welcome quality-focused individuals like yourself to visit our factory for firsthand inspection. We are not afraid of comparison; we fear only those who prioritize price over everything else and overlook the stories behind the prices.

All our chemical materials surpass industry standards. For example, our antioxidants, clay, and calcium carbonate are priced at least ten times higher than industry norms because we prioritize product quality above all else.

High-quality products are inseparable from high-quality raw materials. Therefore, high-quality rubber expansion joints must have high-quality raw materials. Shanghai Songjiang Group has its own standards for procuring raw materials. Various rubber materials are strictly executed according to these standards, and only materials from reputable manufacturers are used, eliminating the use of unbranded materials. Particularly important are the minor additives, where we ensure stringent controls.

Moreover, we prioritize stability and quality over price when procuring materials. For instance, we consistently use Yunxiang brand for natural rubber, Kunlun brand from China Petroleum for butyl rubber, Kunlun brand N41E from China Petroleum for nitrile rubber, antioxidant from Sinopec, and ultra-fine calcined kaolin for kaolin.

Our commitment to using branded materials from reputable suppliers reflects our dedication to ensuring the quality and reliability of our products.
