Resins

 

 

  •  High Density Polyethylene

HDPE is the high density version of PE plastic. It is harder, stronger and a little heavier than LDPE, but less ductile. Dishwasher safe.

HDPE is lighter than water, and can be molded, machined, and joined together using welding.

The appearance is wax-like, lusterless and opaque. The use of UV-stabilizators (carbon black) improves its weather resistance but turns it black. Some types can be used in contact with food.

  •  Linear Low Density polyethylene

Ideal resins for down-gauged lids and a variety of parts such as industrial containers, trash cans, automotive parts, closures and similar items.

  •  Low Density Polyethylene

LDPE is the low density version of PE. This has less hardness, stiffness and strength compared to HDPE, but better ductility. It is opaque and only thin foils can be transparent.

LDPE is used for packaging like foils, trays and plastic bags both for food and non-food purposes. Used as protective coating on paper, textiles and other plastics, for instance in milk cartons.

  •   Polyvinyl Chloride

Polyvinylchloride (PVC) is one of the most explored polymers in the world. The material is characterized by a very wide range of properties and its low cost. This explains its use in many applications.

Classical examples of PVC applications are: pipes, fittings, profiles, packaging, cable insulation, sheets, flooring, artificial leather, medical equipment, bottles, and molded articles.

  •   Polypropylene

Polypropylene is an economical material that offers a combination of outstanding physical, chemical, mechanical, thermal and electrical properties not found in any other thermoplastic. Compared to low or high density polyethylene, it has lower impact strength, but superior working temperature and tensile strength.

Polypropylene possesses excellent resistance to organic solvents, degreasing agents and electrolytic attack. It has lower impact strength, but its working temperatures and tensile strength are superior to low or high density polyethylene. It is light in weight, resistant to staining, and has a low moisture absorption rate.

  •   Polyethylene Terephthalate (PET)

Polyethylene terephthalate (PET) is a polyester material that is most often used to make fibers, parts made by injection molding, and containers for food and beverages, pharmaceuticals and make-up.
PET may also be recycled to make carpeting or fiber filling.

Technically speaking, PET is a linear thermoplastic resin that is created by the condensation of terephthalic acid and ethylene glycol. There are several advantages in using PET, especially when it’s being used for packaging. PET does not break easily and edibles stored in PET taste good because it is pure. The substance also provides a long shelf life because it acts as a good barrier to elements outside of the container.

Containers made from PET are also very lightweight and clear. Products look clean and pure because of the crystal clear appearance. Because PET is only 10% of the weight of an identical glass container, it allows for less expensive shipping and handling, saving a significant amount of money for companies around the world.

  •   Polystyrene

Polystyrene is a strong plastic created from erethylene and benzine that can be injected, extruded, or blow molded; making it a very useful and versatile manufacturing material.
It is used for beverage cups and packaging peanuts as well as a building material, with electrical appliances (light switches and plates), and in other household items.

  •   Expandable polystyrene for shape molding & block molding

 

  •   DOP (Dioctyl Phthalate) for PVC plasticizer

DOP is a combustible non-toxic colorless oily liquid with slight odor, used mainly as plasticizer of resin and estramer. It is also used in vacuum pumps.
