Plastics for Chemical Environments | Curbell Plastics
Tabulated data on chemical resistance charts represent the chemical resistance of various plastics under laboratory conditions. That being said, factors such as mechanical loads, temperature, and part geometry can affect the actual chemical resistance of a plastic material when it is used for a particular application.
Sheet Extrusion - Handbook of Plastic Processes - Wiley
The production of plastic sheets represents another major application area of plastic processing. This chapter provides an excellent explanation of sheet extrusion as it relates to process techniques, advances in equipment, and commonly used resins and structures. The basic elements, and the main equipment components are thoroughly examined.

PLASTIC EXTRUSION PROCESS - POLYMER ACADEMY.com
Polycarbonate (PC) EXTRUSION & TYPES: Sheet/film extrusion is used to extrude plastic sheets or films that are too thick to be blown. There are two types of dies used: T-shaped and coat hanger. The purpose of these dies is to reorient and guide the flow of polymer melt from a single round output from the extruder to a thin, flat planar flow. In
A Study of Plastic Extrusion Process and its Defects
types of plastic extrusion: screw extrusion and ram extrusion. A ram extruder is an extruder where, instead of extrusion screw, a ram or plunger is used and a plunger goes through a barrel and pushes out the material under pressure. The ram extruder was the earliest extruder to be used in the plastics industry.
CHEMICAL RESISTANCE OF PLASTICS - Lab Equipment
chemical properties. Good general resistance - minor attack may occur after long periods of storage. Limited resistance - product can be used for brief mixing and measuring. Poor resistance - product becomes unstable on contact with chemical. Clear LDPE HDPE PP PMP (TPX) PVC PC PS ACRYLIC (AC) PTFE PFA NO-50 NO-100 YES-20* YES-180 NO-25 YES-135
Study of the migration of PVC plasticizers | Request PDF
Ester-amide plasticizer was added up to 40 phr in PVC; and the prepared PVC sheets were characterized for mechanical, X-ray diffraction, thermal, rheological, colorimetric, and exudation properties.
The Effect of Chemicals and Solvents on Plastics -An
The presence of a foreign substance on or within a polymer often affects the mechanical, chemical and thermal properties of the material. The change in strength and rigidity of a polymer resulting from the plasticizing action of a sorbed chemical or due to the withdrawal of an added plasticizer by the leaching operation can seriously affect the useful life of the material.
Technical Data Sheets on Plastic Materials / Manufacturing
DuraFlex 6500 is an engineered polyolefin used primarily as a high gloss cap layer for sheet extrusion and thermoforming of aesthetic articles. This material is supplied in Natural, UV stabilized, and can be colored using typical TPO and PP color concentrates.
An overview of chemical additives present in plastics
Chemicals present in plastics can potentially migrate from the plastic product to the medium in contact with the product and can, also, slowly migrate within the plastic to the surface. Bhunia et al.  has comprehensively reviewed the migration of various chemical substances from plastic packaging materials during MW and conventional heating
