Properties of Plastics and Elastomers
TECHNICAL INFO.
Properties of Plastics Three different polyolefins are included in the plastics used in our chromatography product line – low-density polyethylene (simply called polyethylene in the catalog descriptions), polypropylene, and polymethylpentene. • Low-density polyethylene (L.D.P.E.) is translucent and flexible. The latter property makes this material ideal for items such as our snap caps. This material is also known as conventional polyethylene. • Polypropylene (P.P.), the most rigid of the family of olefins, is also translucent, but can and does come in a variety of colors. This material is used for KIMBLE color-coded caps. Due to its stiffness and overall resistance to chemical attack at room temperature, polypropylene is the material of choice for selected closures. • Polymethylpentene (T.P.X.) is like other polyolefins, is highly resistant to chemical attack at room temperature. Transparency and a relatively high melting point are distinguishing characteristics of this material.
Polytetrafluoroethylene (PTFE) offers unique performance characteristics. This material performs well in aggressive chemical environments, and is totally insoluble with common organic solvents. It is also unaffected by reactive chemicals such as hot concentrated acids and bases.
