High Speed Injection Molding Machine

Physical properties of silica gel.

1. viscosity

Explanation of technical terms: the volume characteristics of anti flow of liquid, quasi liquid or quasi solid substances, that is, the internal friction or internal flow resistance between molecules when flowing under the action of external forces. Generally, viscosity is directly proportional to hardness.

2. hardness

The ability of a material to partially resist hard material pressing into its surface is called hardness. Silicone rubber has a 10 to 80 shore hardness range, which gives designers full freedom to choose the required hardness to best achieve specific functions. Various intermediate hardness values can be achieved by mixing polymer substrates, fillers and additives in different proportions. Similarly, the time and temperature of heating curing can also change the hardness without destroying other physical characteristics.

3. Tensile strength

Tensile strength refers to the force required on each range unit to cause tearing of a rubber material sample. The tensile strength range of the vulcanized silicone rubber is between 4.0-12.5mpa. The tensile strength of fluorosilicone rubber is between 8.7-12.1mpa. The tensile strength range of liquid silicone rubber is between 3.6-11.0mpa.

4. Tear strength

The resistance to apply force to a notched specimen to impede the expansion of the notch or notch. Even if it is placed under extremely high torsional stress after cutting, the hot vulcanized solid silicone rubber can not be torn. The tear strength range of hot vulcanized solid silicone rubber is between 9-55 kn / m. The tear strength of fluorosilicone rubber is in the range of 17.5-46.4 kn / m. The tear strength of liquid silicone rubber is between 11.5-52 kn / m.

5. elongation

It is usually referred to as "ultimate rupture elongation" or the percentage increase relative to the original length when the sample breaks. The general elongation range of hot vulcanized solid silicone rubber is between 90% and 1120%. The general elongation of fluorosilicone rubber is between 159 and 699%. The elongation of liquid silicone rubber is generally between 220% and 900%. Different processing methods and selection of hardener can change its elongation to a great extent. The elongation of silicone rubber is closely related to temperature.

Machine Model Parameter

Medical grade silicone rubber is used to prepare artificial organs, medical devices and their accessories, and various medical pipes. Basic materials of sheet and profile.

The medical grade product silica gel needs to be produced in the clean workshop and inspected to be qualified according to the medical silica gel standard. The high molecular weight polydimethyldimethylsiloxane and chain stopper tetramethyldivinyldisiloxane are copolymerized under the catalysis of catalyst. It has a clear and transparent appearance, good yellow resistance, not easy to deform, high tear resistance, and is suitable for the production of products with high strength requirements .
