Tritan Petralite
Tritan doesn’t contain BPA, BPS or any other bisphenols. Products made with Tritan plastic are clear,
durable, safe and stylish.
Polycarbonate (PC)
Polycarbonate's strength and transparency made it a popular choice for consumer products needing to be
shatter-proof, and also for epoxy resins. PC is also known by various trade names including Lexan, Makrolon
and Makroclear.
Properties: Easily molded, temperature resistance, stiffness, strength, optical clarity.
Polypropylene (PP)
Description: Polypropylene is used for similar applications as polyethylenes, but is generally stiffer and more
heat resistant - so is often used for containers filled with hot food. It too has a simple chemical structure
(many methyl groups of CH3 - one carbon and three hydrogen molecules) making it very versatile. It's
crystallinity (structural order affecting hardness & density) is quite high, somewhere between LDPE and
Properties: strength, toughness, resistance to heat, chemicals, grease & oil, barrier to moisture.
Polyvinyl Chloride (PVC)
Long the second most widely used plastic resin in the world (after polyethylene), PVC (or vinyl). It is still
popular and in common use because of its cost-effective versatility.
Properties:  versatility, ease of blending, strength, toughness, clarity, transparency.
High Density Polyethylene (HDPE)
basic chemical structure of any plastic polymer (repeating units of CH2: one carbon and two hydrogen
molecules) making it very easy to process and thus extremely popular for numerous low value applications -
especially packaging. HDPE has long virtually unbranched polymer chains which align and pack easily
making it dense and very crystalline (structurally ordered) and thus a stronger, thicker form of polyethylene.
Properties: stiffness, strength, toughness, resistance to moisture, permeability to gas, ease of processing.
Polyethylene Terephthalate (PETE)
The most well known member of the polyester family of plastic polymers. It initially gained widespread use as
a wrinkle-free fiber (commonly called "polyester"), and the majority of its production still goes toward textile
manufacturing. It has become extremely popular for food and drink packaging purposes because of its
strong ability to create a liquid and gas barrier - so oxygen cannot get in to spoil food, and the carbon
dioxide that makes drinks fizzy cannot get out.
Properties: clarity, lightness, strength, toughness, barrier to liquid and gas.
