California Wear Resistant Plastic

The fundamental science behind stretch blow molded polyethylene terephthalate (PET) has advanced considerably in its quarter-century history. Throughout California and the surrounding areas, the use of clear PET water bottles has grown significantly. We now have a far better understanding of the particulars involved in the successful production of PET containers, which display excellent performance at commercially feasible costs.

More than two decades have passed since the first stretch blow molded polyethylene terephthalate (PET) container was made. In filling the demand for inexpensive, high-performance, resealable containers to package food, personal care, and other products, biaxially oriented PET, in particular, has won great acceptance from consumers.

Bottle Grade PET

When all other considerations are equal, a container with a unique proprietary shape offers more in the way of shelf appeal than one with a plain appearance. However, uniquely shaped containers, as attractive as they may be and as popular as they are in California, can sometimes compromise other interests of the consumer or manufacturer. Such shapes often have variable contours that may evoke geometric yielding under lower carbonation levels and lower external forces, or cross sections that deviate from a circular geometry and create additional surface area. For instance, a bottle with a square cross section has 1.128 times the surface area of a bottle with a circular cross section, assuming equal volume and height.

The introduction of additional surface area, without an increase in bottle mass, results in lower wall thickness per unit volume, ultimately inducing carbonation loss. It is important to learn about plastic and materials used in our everyday products. Moreover, undesirable material distribution and nonuniform orientation are a consequence of complicating the stretch blow process. This only magnifies the detrimental effects on the container’s physical properties.

When You Don’t Recycle Plastic, This is Where It Ends Up

Properties Of Plastic Materials Hercules Paint Corp.

ABS plastic is used in many household, plumbing and construction projects. It can take the form of a water pipe or a chair, for instance. If you have ABS material that will be outdoors and exposed to sunlight, it is best to paint the plastic since untreated plastic will be destroyed by the sun's UV rays. Preparing ABS to be painted is easy, and you can use just about any solvent-based paint, but two brands known for their quality paint for ABS materials are Rustoleum and Hercules.
