A linear hydrogenated styrene isoprene double block polymer that can be used for thickening fiber optic cable filling paste, cosmetic thickening, and may also be used as a rheological modifier in coatings, adhesives, asphalt, and other fields.

Zhongli has a unique anionic polymerization technology and is the third manufacturer of commercial SEP in the world, after Kolli and Kraton.

Styrene based thermoplastic elastomers are compatible with many polymer materials and exhibit improved performance after blending with other materials. Typically, the improvement in impact strength is most significant, while other properties such as tear strength, stress cracking resistance, low-temperature toughness, and elongation have all been improved to varying degrees. Through special structural design, this type of styrene block copolymer has high polarity and good compatibility with TPU, PC, and PET grade materials. In addition, it can also be used as an interface compatibilizer to blend two incompatible thermoplastic materials.

A high-performance hydrogenated styrene thermoplastic elastomer (HSBC) developed independently, this series of products exhibits good oil solubility, low-temperature performance, and good polyolefin compatibility due to its special intermediate structure. It can be used in the field of oil gel products (jelly wax, adult toys, gel pillow, etc.) and plastic blending modification (covering materials, sealing strips, wires and cables, etc.).

By distributing styrene into the middle segment of the ethylene butene sequence structure of SEBS, a new block copolymer with a certain random distribution of butadiene and styrene is formed. Through selective hydrogenation technology, the product has high hardness and provides high initial toughness and rigidity, endowing the material with weak polarity while retaining the high elasticity of traditional SEBS. Compared with traditional SEBS of the same molecular level, it has lower viscosity and better processing fluidity. It can be widely used in blend formulations, modification of thermoplastic plastics, and modification of adhesives, sealants, coatings, and asphalt.

The Zhongli Q55 series products have excellent stress cracking resistance and can replace flexible PVC for use in toys, packaging, pharmaceutical components, sports goods, wires and cables, and construction products.

Used in fields such as film products or coatings, it is relatively soft and has low permanent tensile deformation. Products with special structural design also have excellent puncture resistance. In addition, its biggest advantage is that it can come into contact with skin and certain foods.

The use of SBC thermoplastic elastomers to modify asphalt can improve its range of use and mechanical properties, while also reducing its low-temperature brittleness. Zhongli modified asphalt SBC products use special polymerization methods to enhance the regularity of molecular chains, forming a more complete network in asphalt and having good compatibility with asphalt. When applied to waterproof coiled material, it can provide better adhesion and durable anti-aging performance.

Adhesives, sealants, and coatings are very important and rapidly developing applications of styrene based thermoplastic elastomers. Styrene based thermoplastic elastomers can be used as adhesives, sealants, and coatings in solution or hot melt form, providing long-lasting antioxidant and UV resistance, as well as excellent weather resistance.
