Resin mainly refers to an organic compound that is solid, semi-solid or pseudo-solid at room temperature, and generally has a softening or melting range after being heated. When it is softened, it is affected by external forces and usually has a tendency to flow. In a broad sense, where can The polymers as the plastic matrix all become resins.

Plastic refers to an organic polymer material made by molding and processing with resin as the main component, adding certain additives or auxiliary agents.

Common types of plastics:

General plastics: polyethylene, polyvinyl chloride, polystyrene, polymethylmethacrylate.

General engineering plastics: polyester amine, polycarbonate, polyoxymethylene, polyethylene terephthalate, polybutylene terephthalate, polyphenylene ether or modified polyphenylene ether, etc.

Special engineering plastics: polytetrafluoroethylene, polyphenylene sulfide, polyimide, polysulfone, polyketone and liquid crystal polymer.

Functional plastics: conductive plastics, piezoelectric plastics, magnetic plastics, plastic optical fibers and optical plastics, etc.

General thermosetting plastics: phenolic resin, epoxy resin, unsaturated polyester, polyurethane, silicone and amino plastic, etc.

Plastic spoons, one of our main plastic products, are processed from food-grade PP raw materials. Including plastic funnels, nasal inhalation sticks, all medical or laboratory supplies or household kitchen utensils are also food-grade raw materials.

Plastic application areas:

1. Packaging materials. Packaging materials are the largest use of plastics, accounting for more than 20% of the total. The main products are divided into:

(1) Film products, such as light and heavy packaging film, barrier film, heat shrinkable film, self-adhesive film, anti-rust film, tear film, air cushion film, etc.

(2) Bottle products, such as food packaging bottles (oil, beer, soda, white wine, vinegar, soy sauce, etc.), cosmetic bottles, medicine bottles and chemical reagent bottles.

(3) Box products, such as food boxes, hardware, handicrafts, cultural and educational supplies, etc.

(4) Cup products, such as disposable beverage cups, milk cups, yogurt cups, etc.

(5) Box products, such as beer boxes, soda boxes, food boxes

(6) Bag products, such as handbags and woven bags

2. Daily necessities

(1) Miscellaneous products, such as basins, barrels, boxes, baskets, plates, chairs, etc.

(2) Cultural and sports articles, such as pens, rulers, badminton, table tennis, etc.

(3) Clothing food, such as shoe soles, artificial leather, synthetic leather, buttons, hairpins, etc.

(4) Kitchen supplies, such as spoons, cutting boards, forks, etc.

That’s it for today, see you next time.
