Polyolefin is a popular and cost-effective material used across a wide variety of industries and markets. Each type of polyolefin resin possesses specific qualities that may make it more or less suitable for a particular application. To ensure a polyolefin material will perform as effectively as possible, Americhem carefully evaluates all ingredients and examines the end product’s intended use. Below are general advantages and disadvantages for product developers to consider when thinking about using a polyolefin plastic as their molding resin.
- Highly durable
- Excellent chemical resistance
- Superb clarity and transparency
- Good weather resistance
- Good flexural and tensile properties
- Good hydrolysis resistance
- Good tear resistance
- Good abrasion resistance
- Good insulating properties
- Good stress crack resistance
- Wide temperature performance range
- Good colorability
- Eco-friendly to produce (no harmful vapors are emitted during processing)
- Reduced energy required for processing
- Water-resistant applications
- Low melting point can limit performance (the HDPE melting point is higher than that of LPDE, allowing it to withstand higher temperatures)
- Prone to light degradation (additives can resolve this issue)
- Inferior shrink resistance
Polyolefins are used in a wide variety of applications where lightweight construction, high tensile strength, puncture resistance, chemical resistance and excellent clarity are required. In the automotive industry, polyolefin plastic materials play an essential role in fuel efficiency due to their light weight. Custom TPO materials allow for just the right feel for armrest skins, consoles, door bolsters and cup holders, while PP materials perform well on bumpers, body panels, trims and door claddings.
Polyolefins are an attractive option for outdoor stadium seats, given that UV, fire and weathering protection can be packaged to meet building standards and requirements. Textile manufacturers use polyolefin fibers to produce apparel items like gloves, activewear and lining fabric because of their excellent water repellent properties. These lustrous fibers have also become a preferred material for carpeting, carpet backing, upholstery and seat covers.
Because polyolefins are considered non-toxic, have extreme clarity and are recyclable, they are a popular and sustainable choice for bottle packaging. Polyolefins also make an excellent food-grade packaging material for container lids.
Americhem can help meet your functional, aesthetic and cost target requirements for these and other polyolefin applications.
Americhem’s polyolefin products can be custom developed for extrusion, injection molding, blow molding and compression molding manufacturing methods. Our polyolefin base resins include:
- Polypropylene (PP)
- Polyethylene (PE)
Americhem’s high-performance polyolefin formulations can help you achieve better tensile strength, tear resistance, stability, density and colorfastness under ambient and non-ambient conditions. Our polypropylene, polyethylene and polybutylene resins may be blended with carbon fibers, glass fibers, UV additives, flame retardant additives, antimicrobial additives, lubricant additives, custom color resins and other product additives to enhance their mechanical properties and improve certain aspects of their performance and processability.
