Investigation of charge transport properties in conducting …

The conductivity of the blown polymers blended with LDPE was in the range 10 −12 –10 −6 S cm −1, showing their potential use as antistatic materials for the encapsulation of electronic equipment. The DC conductivity of all self‐doped homopolymers and PTSA

Role of heat transfer and thermal conductivity in the …

The thermal conductivity of polypropylene–filler composites was estimated with a standard model for various fillers such as calcium carbonate, talc, silica, wollastonite, mica, and carbon fibers. The rate of cooling under given conditions, including the melting temperature, mold wall temperature, mass of the composite, and filler content, was estimated with standard heat‐transfer equations.

TECHNICAL WHITEPAPER Low Temperature Properties of Polymers Introduction Most plastics at room temperature show their familiar properties of flexibility (a low Young’s modulus) and high resistance to cracking but when the temperature decreases this

High-density polyethylene - Wikipedia

High-density polyethylene, unlike polypropylene, cannot withstand normally required autoclaving conditions. The lack of branching is ensured by an appropriate choice of alyst (e.g., Ziegler–Natta alysts) and reaction conditions. HDPE is resistant to many.
