Bio-based sponge

　　YIBAO NR·BIO – USDA certified bio-based rubber sponge for more environmentally friendly wetsuits, vulcanized shoes, sporting goods, and automotive applications.

　　As the international call for environmental protection grows louder, people are increasingly in need of purchasing eco-friendly products. However, diving suits, vulcanized shoes, sporting goods, and the automotive sector are made from petroleum products, which begin with oil exploration and drilling. In the process of refining into finished products, they will cause environmental pollution as well as water, soil, and other natural pollution. With 20 years of experience in understanding the properties of rubber sponge materials and 3 years of hard work, Yibao has developed a sponge material that can prevent us from further damaging the earth. This rubber sponge is called YIBAO NR: BIO. Diving suits, vulcanized shoes, sporting goods, and automotive sectors made from natural resources such as shellfish, seafood shells, and rubber – rubber sponges that do not contain petroleum rubber. The bio-based rubber sponge made by Yibao has been certified by the US Department of Agriculture

　　In recent years, Yibao has been talking and communicating with customers, requiring high performance in rubber and hoping to incorporate environmentally friendly processes in rubber production. Non-toxic, water and air pollution treatment, material reuse and recycling, or biodegradable chemical applications, any of which can help establish corporate social responsibility in different ways. Yibao foresaw this emerging direction of the rubber industry, namely green and environmental protection, and began to understand and find suitable materials to transform petroleum-based rubber sponge into bio-based and sustainable products.

　　Yibao is located in the southeast coast of Fujian, which is rich in tea and a large amount of seafood is consumed every year, including shells, oysters and seafood. The remaining shells, oyster shells and other shells are piled up like mountains and a large amount of tea stems are left. In addition, Yunnan and Hainan provinces in China have natural rubber resources. Using natural resources to make rubber sponge sheets can not only reduce the carbon footprint of transportation, but also solve the waste problem. Therefore, diving suits, vulcanized shoes, sports goods, and automotive fields are sustainable. In response to the demand of brands and customers for rubber sponges with sustainable properties, three years later, bio-based rubber sponges made of natural rubber came out, namely YIBAO NR·BIO.

　　USDA-certified bio-based sponge YIBAO NR·BIO reduces carbon footprint by 52%, with 52% of the carbon coming from renewable resources.

　　YIBAO NR·BIO is a range of selected rubber sponges, labeled according to their hardness, density, tensile and tear properties, rubber content and variations in ASTM testing. Polymer sponge YIBAO NR·BIO is made from green natural resources, using eco-renewable rubber, tea stems and vegetable oils, and recycled shellfish shells. From raw material preparation, manufacturing to final delivery, the carbon footprint is reduced by 52%. In addition, according to ASTM-D6866, 52% of the carbon comes from renewable resources.

　　Polymer sponge YIBAO NR·BIO is made from green natural resources such as shellfish shells, natural rubber, tea stems, etc.

　　52% Sponge with Bio-based Rubber – Sustainable physical properties.

　　Customers can choose the appropriate environmentally friendly recycled rubber sponge to use with their environmentally friendly recycled fabrics and fabrics. Rubber sponges that reduce fossil resources can be made into different products, such as wetsuits for surfing, swimming, diving, vulcanized shoes, sporting goods, and the automotive field. YIBAO NR·BIO rubber sponge wetsuits are still soft, light, flexible, and durable. It also meets ASTM standards. Whether you are designing wetsuits with various metal zippers, surfing suits, or vulcanized shoes, sporting goods, automotive fields, or wetsuits for different high and low water temperatures, there are a variety of selected sponges to provide products for various fields for you to choose from. YIBAO NR·BIO has achieved great success since its launch, and some customers have named their products to indicate that they are environmentally friendly and low-carbon product suppliers.

　　Fossil-resource-reducing rubber sponge – YIBAO NR·BIO – can be made into various products, such as diving suits, vulcanized shoes, sports goods, automotive fields and many other products.

　　Natural resources include rubber trees, tea stems, vegetable oils, shellfish shells, and natural rubber trees.

　　Yibao is a rubber sponge manufacturer with 20 years of experience in synthetic rubber manufacturing. It provides bottom-level design technology and cooperates with customers to jointly develop functional rubber sponges. If you are looking for a sponge manufacturer that can provide bottom-level design technology and cooperate with customers to jointly develop functional rubber sponges and has a sense of social responsibility, Yibao is your best choice.
