Overview of the Silicone

Silicone

Silicones are polymers that include any inert, synthetic compound made up of repeating units of siloxane. They are typically heat-resistant and rubber-like, and are used in sealants, adhesives, lubricants, medicine, cooking utensils, and thermal and electrical insulation.

Some common forms include liquid silicone oil, soft silicone gel, silicone rubber and regidity silicone resin, and silicone caulk.

Characteristics /Properties

  • Low toxicity
  • Low thermal conductivity and thermal stability
    Thermal conductivity
    is the property of conducting heat. The material, Silicone, of low thermal conductivity is often used as the purpose of thermal insulation. With the characteristic, the material provides high stability when being processed through a wide temperature range of -40℃~200℃ which makes the adhesion of different materials a significant technique to perform
  • Low chemical reactivity
  • Impact resistant
  • The ability to repel water and form watertight seals
  • Does not support microbiological growth
  • Resistance to oxygen, ozone, and ultraviolet (UV) light This property has led to widespread use of silicones in the construction industry (e.g. coatings, fire protection, glazing seals) and the automotive industry (external gaskets, external trim).
  • Electrical insulation properties silicone can be formulated to be electrically insulative or conductive, it is suitable for a wide range of electrical applications.
  • No "marked harmful effects on organisms in the environment" have been noted for silicones. They are non-biodegradable but are absorbed by solids in waste water treatment facilities. Degradation is catalyzed by various clays.

Products & Applications

The end products may take on diverse consistencies as hard plastic, rubber, gels, and liquids based on different demands and applications.

The liquid types-LSR, Liquid Silicone Rubber (so called LIMS, Liquid Injection Mold system), is extensively used in a wide range of industries and favored by infant-care, food container and medical device manufactures.

Mainly, silicone-made products benefit as high elongation, superior tensile strength, tear strength, resistance to extreme temperatures, and bacteria resistance.

The properties have contributed to the use of silicones in medical applications involving seals, plungers, valves, and gaskets in implanted and non-implanted devices. Common applications are skin protecting composition, prosthesis, seat cushion......etc.


Thermoplastic Polyurethane High Tech Film

Thermoplastic polyurethane is an advanced and high-performance technical film. It has excellent flexibility, durability and properties.

It could be used on various applications. Film could be bonded with fabric and work as an intermediate, great hydrolysis resistance and excellent UV stability are always good to use in medical products, great elongation performance is fabulous to shape and a eco-friendly material as bio-degradable.

Waterproof property is the primer choice to cover and protection. Soft, non-toxic, odorless, free of all plasticizers and softness are good to wrap silicone gel and maintain the shape and properties of silicone gel.

The table below is going to show why Thermoplastic polyurethane is preferable to other plastic films in terms of properties comparison.

TPU film comparison
  • Abrasion Resistance of High Tech TPU is 3-5 times stronger than Rubber. (In accordance with TABER test, Load 1000g, 23℃ Total cycles :5000)
  • Green Material: Bio-based made and Hydrolyzed.
  • Microbial Resistance: When hygiene is a concern, the polyether-based TPU films are the best choices to protect materials from microbial attacks such as bacteria and mildew.
