HDPE Plastic and Polypropylene (PP) is considered as a partially crystalline thermoplastic polymer, which is obtained from the polymerization of propylene and belongs to the group of polyolefin’s.
It is a very hard and resistant plastic, it is opaque and with great resistance to heat because it softens at a higher temperature of 150 ºC). It is very resistant to shock although it has low density and can bend very easily, resisting multiple bends. It is of High Impact Acrylic Polypropylene
It offers a very favorable resistance to weight ratio and excellent chemical resistance for use in highly corrosive environments. Natural Homopolymer Polypropylene is easy to handle to manufacture tanks and process equipment. Also used as in the protective coating of metals in corrosive chemical processes. For its excellent conformability and the consistency of the material in the thermoforming; High Impact Poly Styrene sheet is already a standard in the prosthetic and orthotic industry.
Characteristics of polypropylene
Among the characteristics of polypropylene, you can find:
- It has great resistance against various chemical solvents, as well as against alkalis and acids.
- Polypropylene has multiple applications, which is why it is considered one of the most developed thermoplastic products in the future.
- It is an inert product, totally recyclable, its incineration does not have any polluting effect, and its production technology has the lowest environmental impact.
Types of polypropylene
Within the wide variety of polypropylenes that exist for different industrial applications, there are three important types, which are classified as follows:
Polypropylene copolymer
This type is obtained by medium impact copolymer with good dimensional stability and good impact resistance at low temperatures with low odor and flavor transfer. Especially, it is for injection molding and thermoforming.
This can be used in:
- Toys
- Food packaging
- Furniture
- Household items
Polypropylene homopolymer
Excellent process ability and resistance to carrying water, good melt stability. Especially, for extrusion molding of oriented applications is raffia and monofilament.
This can be used in:
- Raffia
- Threads, twine and Nylon Rod
- Strip
- Rope
- Injected items
- Thin wall containers
Polypropylene random copolymer
It has excellent clarity and good impact resistance. It is especially for injection molding.
This can be used in:
- Home furniture
- Containers
Uses and applications of polypropylene
Its extensive line of polypropylenes is used in injection, extrusion and blowing processes and includes homopolymers, impact copolymers and random copolymers. It is used in a wide variety of applications including packaging for food, textiles, Polypropylene Sheet, laboratory equipment, automotive components and transparent films.
From the industrial processes, an endless number of different polypropylene products can be prepared, whose properties vary according to the length of the polymer chains (molecular weight), their polydispersity, the co monomers eventually incorporated, etc. These basic characteristics define the mechanical properties of the material and its final applications. Literally speaking of different types or grades of polypropylene. For all this, the great diversity of products produced with this polyolefin allows you to have applications as varied as:
- Auto parts
- Buckets, containers, bottles
- Furniture
- Polypropylene Sheet
- Films for food packaging
- Fibers and filaments
- Bags and pockets
- Background of carpets
- Foam PVC, Diapers, sanitary napkins, clothes
