What Makes Polystyrene(PS) Plastic Disposable Cutlery Outstanding
- Apr 27, 2017 -

Polystyrene (PS) is a synthetic aromatic polymer made from the monomer styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight. It is a rather poor barrier to oxygen and water vapor and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several billion kilograms per year. Polystyrene can be naturally transparent, but can be colored with colorants. Uses include protective packaging containers (such as “clamshells”), lids, bottles, trays, tumblers, and disposable cutlery.

As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled. This temperature behavior is exploited for extrusion (as in Styrofoam) and also for molding and vacuum forming, since it can be cast into molds with fine detail.

All Dexuan disposable cutlery come with 100% food grade PS plastic material.
You are welcome to have the following questions:
What makes food grade PS plastic outstanding?
Is it safe for use in food service products?
Will it release dangerous substance in high temperature?
Dexuan’s imported food grade PS plastic disposable cutlery mainly have the following two chemical advantages:
1.High transmittance.
Featured in Colorless, Tasteless and Non-toxic,food grade disposable PS cutlery is cleaner as its transmittance is 88-92% ,which is second only to acrylic polymer,and with high index of refraction from1.59 to 1.60.
2.Corrosion resistant.
Featured in extremely efficient in preserving heat,food grade disposable PS cutlery will not scald oneself up to 80 ℃ as its light weight,high hardness and corrosion resistance.
