There are significant differences between ordinary liquid injection silicone and screen printing silicone in many aspects. The following is a detailed comparison of the two types of silicone:
Ordinary liquid injection silicone
Material state
Liquid, pre-mixed liquid silicone rubber (LSR), two-component material, good fluidity.
Molding process
Liquid molding (LIM) or injection molding (Injection Molding) process is often used. Liquid silicone is injected into the mold cavity by an injection machine and heated to cure.
Product characteristics
1. Good fluidity: can easily fill complex-shaped molds to ensure high-precision molding of products.
2. Fast vulcanization speed: high production efficiency.
3. Excellent elasticity: It has good elasticity and softness after curing.
4. Chemical corrosion resistance: It has excellent resistance to chemicals such as acids, alkalis, and solvents.
5. High temperature resistance: It can maintain stable performance in a wide temperature range.
Application areas
1. Medical industry: such as seals, medical equipment components, etc., because of their biocompatibility and high temperature resistance.
2. Electronic industry: such as sealing, fixing, encapsulation, protective covers, etc. of electronic components, because of their good waterproof and moisture resistance.
3. Automotive industry: such as engine sealing, suspension system and brake system sealing, shock absorption and vibration prevention.
4. Others: such as structural sealing, mold making, etc.
Cost-effectiveness
Liquid molding equipment has relatively low investment, but high production efficiency, high material utilization rate and less waste.
Ordinary liquid injection silicone
Material state
Liquid, two-component liquid silicone, composed of flowing transparent liquid silicone, curing agent and color paste (color adjusted as needed).
Molding process
Suitable for screen printing process, it can be firmly adhered to the surface of textiles, non-woven fabrics, leather, imitation leather and other materials through screen printing.
Product characteristics
1. Moderate viscosity: easy to operate, high transparency of the product.
2. Strong adhesion: printed products do not delaminate and can be color-coated.
3. Soft touch: The silk-screen pattern has a strong three-dimensional sense and a soft touch.
4. Good water washing fastness: The silk-screen pattern has excellent peel strength, abrasion resistance, and brightness.
5. Environmentally friendly and non-toxic: It meets food grade and safety standards.
Application areas
1. Clothing factory: such as clothing labels, clothing patterns, etc., to provide unique decorative effects.
2. Hat factory, shoe factory: such as anti-slip decoration of shoes, anti-slip of socks, etc., to provide anti-slip and durable characteristics.
3. Luggage and handbag factory: such as handbags, travel bags, bags, labels, bag decorations, etc.
4. Crafts factory, embroidery factory: such as high-end electronic potting glue, etc.
Cost-effectiveness
It is suitable for small batch and multi-variety production, and the cost-effectiveness depends on the printing process and the added value of the product.
Summary:
Material state and molding process: Ordinary Liquid injection silicone is a liquid silicone rubber with good fluidity, suitable for injection molding or liquid molding process; silk screen silicone is a two-component liquid silicone specially used for silk screen printing, which adheres to various material surfaces through printing process.
Product characteristics: Both have good elasticity and softness, but silk screen silicone pays more attention to printing effect and adhesion, while liquid injection silicone pays more attention to product precision and molding efficiency.
Application fields: Liquid injection silicone is widely used in medical, electronic, automotive and other industries, which have high requirements for product precision and performance; screen printing silicone is mainly used for decoration and anti-slip treatment in clothing, bags, handicrafts and other fields.
Cost-effectiveness: Liquid injection silicone is suitable for large-scale production, with high production efficiency and high material utilization;
screen printing silicone is suitable for small batch and multi-variety production, and the cost-effectiveness depends on the printing process and the added value of the product.
When choosing, it should be comprehensively considered according to factors such as specific application scenarios, product requirements and production costs.
