Hydrogenated Styrene-Butadiene Block Copolymer SEBS Yh-688 Is Used for Medical Devices

Product Description

Rubber SEBS YH-688 is a thermoplastic rubber. Appearance: White or light color, powder or uniform granular, free of mechanical impurities and oil.
Styrene content: about 13% (by weight).
Structure: Star.
Tensile strength: ≥10MPa.
Elongation at break: ≥800%.
300% constant elongation stress: ≥1.4MPa.
Tear deformation: ≤4%.
Shore A hardness: ≥45A.
Melt flow rate (MFR) : 0.8-3.0g/10min (5kg, 200ºC).

The uses of rubber SEBS YH-688 mainly include the following aspects:
Plastic modification:
Blending with polypropylene (PP) and other plastics can improve the flexibility, impact resistance and aging resistance of plastics.
Coating material: can be used to cover wire and cable, play the role of insulation, protection and increase flexibility.
Wire field: Used to manufacture all kinds of wire, such as headphone cable, data cable, etc.
Halogen-free fuel: due to its good flame retardant performance and halogen-free, it meets the requirements of environmental protection and can be applied to occasions with higher requirements for flame retardant performance, such as building materials, electronic equipment shells, etc. In the event of a fire, it can effectively slow the spread of the fire and reduce the fire risk.
Sealing strip: can be used to manufacture doors and Windows, automobiles, electrical appliances and other products sealing strip.
Medical devices: Because of its good biocompatibility, non-toxic and tasteless, aging resistance and other characteristics, it can be used to manufacture some medical devices, such as infusion tubes, medical gloves, catheters, etc.
Daily necessities and sports equipment: can be used to manufacture handles, stationery, toys, sports equipment and other products. For example, the application of the handle of the fitness equipment, the grip of the bicycle, and the children's toys can provide a comfortable feel and good impact resistance.
Adhesives and sealants: can be used as an ingredient in adhesives and sealants for bonding and sealing various materials.
