Features Of Toy Silicone

2022-11-05

Toy silicone is a kind of synthetic rubber, which belongs to organic silicone and is specially used for toy production. Toy silicone is the best silicone rubber that is resistant to both high temperature and severe cold. Generally, it can maintain good elasticity at -60~250 ° C, and has high stability to thermal oxidation and ozone. Toy silicone is non-toxic and harmless to children. It is harmless to the body, insulated, and has high chemical inertness. It is an ideal raw material for toy production. Toy silicone is also known as: toy silicone rubber, toy glue, toy silicone, toy silicone, toy silicone.

Toy Silicone Chemical
The thermal expansion coefficient and thermal conductivity are 2-2.5 times and 2-3 times that of organic rubber, respectively. Silicone rubber solubility parameter δ=7.3-7.6, soluble in benzene, toluene and xylene.

Features of toy silicone
①It has good operability.
②Low viscosity, good fluidity and easy operation.
③ The shrinkage rate is small, generally less than two thousandths.
④ Good tensile strength.
⑤ Not easy to deform.
⑥The hardness of silicone rubber should be suitable for product use.
⑦High temperature resistance, more mold turning times, longer service life, better, acid and alkali resistance and aging resistance.
⑧ Non-toxic and harmless, strong chemical inertness.

Toy Silicone FAQ
1. Will the toy silicone be burnt?

Because unsaturated resin and resin products are added with peroxide curing agent, they will generate a lot of heat when they react with the resin. Generally, the curing time of resin is 3 minutes, so it is necessary to release the mold as soon as possible after 3 minutes to prevent the silicone mold from not being damaged. The phenomenon of mold burning occurs.

2. Will the toy silicone appear dry on the outside?

Toy silicone is a condensation type silicone, which is cured by absorbing moisture in the air. In the process of making silicone, the moisture is evaporated to dryness without adding an appropriate amount of moisture. This phenomenon will occur.

Solution: This phenomenon is not a product quality problem, but because the water is not controlled, the storage period of the silica gel is increased, and the shelf life is long, and some phenomena will occur. As long as the silica gel is used, an appropriate amount of 0.05% water is added and stirred evenly. Some situations can be resolved.

3. Will the toy silicone have poor tension?

In the process of making the mold, in order to reduce the viscosity of the silica gel and make the silica gel easy to handle, a large amount of silicone oil is added to the silica gel, which will make the silica gel very soft, resulting in inability to pull and reduce the tear strength. The phenomenon of poor tensile force, resulting in the phenomenon that the mold is not durable, the service life is short, and the number of mold overturns is small.

4. Will the mold not be resistant to acid and alkali, and not resistant to aging?
In the process of making silicone molds, we recommend that customers do not add any silicone oil. If necessary, the amount of silicone oil added should not exceed 5% to 10%.Because the addition of too much silicone oil will destroy the molecular weight of the silica gel, the resulting mold will not be resistant to acid and alkali, and is not resistant to aging.

We also sell Silicone Case, which is generally made of rubber, soft and elastic, and is often used to protect electronic digital products from accidental drops or wear. If you need a Silicone Wristband, you can also consult us. Silicone wristbands are more associated with various organizational activities, brand promotion, sports, etc. A good design can convey a profound meaning.
