The hardness of liquid silicone is wide range, from 0°A to 100°A, every 5 degrees in a unit, delicately divided, providing infinite possibilities for different application scenarios. Among them, addition silicone, as a leader in liquid silicone, is favored for its unique properties.

According to the different hardness, the addition liquid silicone is divided into three categories: high hardness, medium hardness and soft hardness, and each hardness of the silica gel has its own characteristics to meet diverse needs.

Very soft silicone (0°A) exhibits extremely high flexibility with its excellent elongation and relatively low tensile strength, while mold silicone has a low tear strength but a high elongation, making it an ideal choice for children's toys, models, etc. that require soft, curved, stretchable or swinging properties.

Soft silicone (5-10°A) finds the perfect balance between elongation and tensile strength, making it the material of choice for a wide range of applications such as soft gaskets, gaskets and automotive parts.

Medium hardness silica gel (20-30°A) increases the hardness while maintaining a certain elasticity, making it more rigid and compressible, so it is often used in electronic product shells, protective cases and other occasions that require a certain support force and protection.

Partial hard silicone (40-50°A) has moderate hardness, elasticity and compressibility, making it widely used in automotive seals, molds, anti-slip mats and other fields, showing excellent sealing and durability.

With its very high hardness, combined with good wear resistance and high temperature resistance, hard silicone (60-90°A) has become the first choice for making injection molds, various joints, sealing rings, wear-resistant parts and other components that require high strength and durability.

The superhard silicone, usually with a hardness of more than 90°A, is widely used in industrial fields in extreme environments, such as high-temperature resistant parts, acid-alkali resistant containers, etc., with its excellent high temperature resistance, acid and alkali resistance, and wear resistance.

In conclusion, with its rich hardness options and diverse performance characteristics, additive liquid silicone provides an efficient and reliable solution for all walks of life, covering a full range of needs from soft to hard, from ordinary to special.
