Polypropylene (PP) is a member of the polyolefin family of plastics. Polyolefins are one of the so-called commodity thermoplastics. The polyolefin family includes PP, polyethylene, polybutylene, and various other derivatives.
Polypropylene has turned out to be the most versatile of the polyolefin family, accounting for the continuing rapid increase in its use, approximately 8% in 2021. It is highly versatile due to a combination of factors. These factors include excellent chemical and heat resistance a good balance of physical and mechanical properties, a very favorable strength-to-weight ration and low taste and odor characteristics.
The main characteristics observed in Polypropylene family are –
Polypropylene is increasingly displacing a number of other materials in a variety of applications. Typically, one or more of the following reasons is given for replacing another material with polypropylene:
There are two major types of polypropylene available in the market –
Polypropylene Homopolymer is the most widely utilized general-purpose grade. It contains only propylene monomer in a semi-crystalline solid form. Main applications include packaging, textiles, Construction, healthcare, pipes, automotive and electrical applications.
Polypropylene Copolymer family is further divided into random copolymers and block copolymers produced by polymerizing of propene and ethane:
Material Characteristics, Test Standards and Typical Results of PP Extrusion
In general, skin irritation has not been produced in human patch tests with PP Resin. However, a small percentage of subjects may respond to prolonged contact with redness of skin. Significant skin permeation, and systemic toxicity, after contact appears unlikely. There are no reports of human sensitization.
If particles of PP Extrusions contact the eye, mechanical irritation with tearing, pain or blurred vision may result.
None of the components present in this material are carcinogenous.
Various colors. Solid. No serious effects anticipated under normal conditions of use. No known applicable information.
Inhalation : No specific intervention is indicated as the molding is not likely to be hazardous by inhalation. Consult a physician if necessary. If exposed to fumes from overheating or combustion, move to fresh air. Consult a physician if symptoms persist.
Eyes : Not applicable under normal conditions of use.
Ingestion : No specific intervention is indicated as molding is not likely to be hazardous by ingestion. Consult a physician if necessary.
Skin : The molding is not likely to be hazardous by skin contact, but, cleansing the skin after use is advisable. If molten polymer gets on skin, cool rapidly with cold water. Do not attempt to peel molding polymer from skin. Obtain medical treatment for thermal burn.
Pre-existing eye, skin and respiratory disorders may be aggravated by exposure.
Fillers are encapsulated and not expected to be released from product under normal conditions of use.
2. Incineration with Energy Recovery
The high fuel value of this product makes option 2 very desirable for material that cannot be recycled, but , incinerator must be capable of scrubbing out acidic combustion products. Treatment, storage, transportation, and disposal must be in accordance with applicable federal, state/provincial, and local regulations.
Package the Product in Paper, Plastic Film or Carton Box in order to minimize surface exposure.
Store Under normal Warehouse Conditions in cool, dry and ventilated area.
PP Block Copolymer Resin is not a skin irritant in tests with animals.
In animal testing PP Block Copolymer Resin has not caused carcinogenicity. No animal data are available to define developmental, reproductive or mutagenic hazards.
No information is available. Toxicity is expected to be low, based on insolubility in water.
With appropriate commercial practices, the Poly-Propylene Extrusions are safe to handle and in storage. For further information on the material or this MSDS, please contact the Technical Director at R.K. PROFILES PVT. LTD., Faridabad, India.
