What is the difference between novelty silicone ice cube trays and plastic? Some people may have known that silicone ice  trays are made of food gade bpa free silicone raw material. For silicone and plastic PE: one is rubber, the other one is plastic. One is a thermosetting polymer, the other is a thermoplastic polymer.

When heated, silicone will not be soften and repeatedly with molding, silicone is not dissolved in the solvent. PE plastic flow deformation can occur when heated, and while cooled, it can keep the nature of a certain shape. Easy for extrusion and injection or blow molding processing.In a certain temperature range, can soften and cooling hardening again and again.

Silicone rubber is a kind of highly active adsorption material, which insoluble in water and any solvent, non-toxic tasteless, stable chemical properties, in addition to the strong alkali, hydrofluoric acid does not react with any material. Various types of silicone because of the different manufacturing methods and form different microporous structure.Chemical components and physical structure of the silica gel, determines it has many other similar materials difficult to replace features: high adsorption properties, thermal stability, chemical stability, has high mechanical strength, etc.

Silicone according to the size of the aperture is divided into: macroporous silica gel, coarse pore silica gel, b-type silica gel, silica. Plastic is a kind of high molecular weight organic material as the main composition of the material, it in the finish machining in solid shape, in the process of manufacturing and processing, can borrow flows to modelling.
