Summary of Common Quality Problems of Silicone Products

Silicone rubber product is a kind of silicone products of silicone processing molding. Silicon rubber product have high temperature resistant, easy cleaning, long service life, flexible, comfortable, environmental protection, non-toxic, and other characteristics, its application in our daily life is very extensive, common silicone products are silicone pacifiers, silicone tube, silicone cake mold, silicone kitchenware, silicone keys, silicone bracelet and silicone cases, but in the process of the actual use of silicone rubber products, some people will encounter all sorts of problems; Today, niceone-tech will introduce the causes and solutions of common quality problems in silicone products, hoping to help friends in and out of the industry.

1. Dark marks of silicone products

Causes: the molding temperature of the silicone product exceeds the bearing range of the color paste, which will lead to water ripple after the silicone molding

Solution: control the temperature within the tolerance range of the paste

2. Silicone rubber keypad products turn yellow

Causes: when silicone products are used for a long time, the surrounding ring will turn yellow to silicone rubber keypad products;

Solution: by adding anti-yellowing agent or using better silicone materials, such as food grade silicone, liquid silicone and weather glue.

3. Silicone rubber keypad products absorb dust

Cause: Silicone rubber material contains silicone desiccants, which have a strong adsorption force on the dust in the surrounding air.

Solution: Through the production of silicone rubber keypad products in the dust-free workshop, silicone rubber keypad can reduce the contact with dust; Or the method of spraying hand oil on the surface of silicone rubber keypad products to reduce the adsorption of dust.

4. Silicone products produce oil

Causes: the mixing of silicone oil and white mineral oil in the silicone raw material leads to the conflict with white carbon black, resulting in oil production;

Solution: control the amount of silicone oil and mold release agent. Silicone oil of silicone rubber raw material will conflict with highly corrosive chemicals and need to use alkaline substances to increase the adhesion;

5. Moldy silicone products

Causes: some additives in silicone raw materials are the main factors leading to mildew, such as silicone oil, rubber powder, vulcanization agent, etc., they are the main nutrients to promote the growth of mold; Storage environment wet environment will promote the growth of mold silicone products;

Solution: the storage warehouse should be dry and ventilated, check whether there is any problem with the silica gel products regularly, and use alcohol or anti-mildew agent to deal with the moldy silica gel products.

6. The tension of silicone products is poor

Causes: The reason is that in order to shorten the molding time of silicone products, the silicone rubber keypad manufacturers increase the product output by adjusting the pressure and temperature of the machine. On the one hand, many defective products are likely to appear in the products, and on the other hand, the service life of the products will be shortened.

Solution: adjust the machine to suit the temperature of the molding mold of the silicone product, and extend the time of the hydraulic molding.

Due to the differences in equipment technology and experience of some silicone product manufacturers, the causes and solutions of the problems will be different.
