How to distinguish liquid silicone products from flat silicone products?

2024-01-17

The production of silicone products is inseparable from the silicone molding process, and the silicone molding process is divided into two categories: solid silicone molding process and liquid silicone molding process according to different products and different silicone raw materials. The solid silicone molding process is what we call Flat press silicone.

1. Liquid silicone products

Liquid silicone, as the name suggests, has fluidity. Different from flat-pressed silicone, the silicone is made by mixing and letting it stand before being injected into the material tube for injection molding. Products produced by liquid silicone are generally common to consumers, such as baby products, kitchen supplies, medical supplies and other products that have relatively high quality requirements, are environmentally friendly, non-toxic and tasteless, such as baby pacifiers, stethoscope silicone covers, etc. These liquid silicone The product is high temperature resistant, has a smooth surface, no defects, holes, joints, grinding marks, etc., and no vulcanizing agent is added during the production process. However, in comparison, the mechanical properties of liquid silicone products are not as good as those of flat-pressed silicone products. They must be carefully cared for and the pressure cannot be too high, such as baby pacifiers and baking molds. After use, they should be cleaned with hot water and air-dried. Dry.

2. Flat pressed silicone products
Flat-pressed silicone is molded using a pressure molding machine at a certain temperature. It is actually uses solid silicone material. It has no fluidity and is a solid piece that needs to be processed through various processes before being molded. Flat-pressed silicone products have gone through great pressure and heat tests during the production process. Therefore, flat-pressed silicone is often used in heat-resistant and pressure-intensive products. However, the surface of the product is not as strict as liquid silicone products, and there are no other special features. Require. Flat-pressed silicone products in daily life are commonly used in industrial miscellaneous parts, silicone rubber auto parts and other products that are generally heat-resistant, odor-resistant, and UV-resistant, such as laminating rollers, water squeezing rollers, and bridge rollers near static machines. Products that do not come into direct contact with the human body are also used in a wide range of applications.

Use the right product in the right place. Liquid silicone and flat silicone are both silicone production processes, but their uses are different, and the performance of the products produced is also different. Choose a suitable method to produce products suitable for consumers.
