There are significant differences between liquid silicone and medical liquid silicone in many aspects. The following is a detailed analysis of the differences between the two:
1. Definition and properties
Liquid silicone: It is a liquid material relative to solid high-temperature vulcanized silicone rubber. It has the characteristics of good fluidity, fast vulcanization, and safer and more environmentally friendly. It can fully meet food grade requirements and is widely used in infant products, medical supplies and electronic products.
Medical liquid silicone: Specifically refers to liquid silicone used in the medical field. It is a non-toxic, environmentally friendly, odorless silicone material with good physiological inertness and a variety of excellent properties. It is widely used in electronics, aerospace, medical, food hygiene and other industries, especially in the medical field, such as baby pacifiers, molar sticks, medical catheters, medical gaskets and other products in the production and development.
2. Performance characteristics
Liquid silicone:
Good fluidity: It can fully fill every corner of the mold and produce fine products.
Fast vulcanization: Under appropriate conditions, it can quickly solidify into an elastomer.
Safe and environmentally friendly: It can fully meet food grade requirements and is non-toxic and harmless.
Excellent properties: such as tear strength, resilience, anti-yellowing, thermal stability, water resistance, good air permeability, heat aging resistance and weather resistance.
Medical liquid silicone:
Non-toxic and tasteless: ensure safety in medical use.
Physiological inertness: good compatibility with human tissues and will not cause adverse reactions.
Chemical corrosion resistance: able to remain stable in a variety of chemical environments.
High temperature resistance: can reach 300℃, suitable for medical applications in high temperature environments.
Good fluidity and easy perfusion: easy to process into medical products of various shapes and sizes.
3. Application areas
Liquid silicone:
Infant and toddler products: such as pacifiers, molar sticks, etc.
Medical supplies: such as medical catheters, medical gaskets, etc. (but not necessarily all meet medical grade standards).
Electronic products: such as buttons, mobile phone cases, etc.
Other fields: such as handicrafts, mold manufacturing, etc.
Medical liquid silicone:
Medical devices: such as medical catheters, medical gaskets, artificial organs, etc.
Baby products: such as pacifiers, bottles, etc. (must meet medical grade standards).
Other medical-related products: such as seals and insulation parts of medical equipment.
4. Storage and use
Both need to be stored in a dry, ventilated, and cool environment, avoiding direct sunlight and high temperatures. The corresponding operating procedures and safety standards must be followed when using.
