Please allow at least 4mm in your cutting allowance calculations for the width of the saw cut
We use table saws and horizontal band-saws, so edges will have a sawn finish
We only use sawing equipment, so we are unable to offer high precision items
Tolerances are +2mm to minus 0mm
We aim to cut as squarely as possible although incoming materials are sometimes out of square
We are unable to cut or machine shapes but we are happy to obtain a custom quotation for machined shapes or parts (please call us on 0114 2560889)

PVC Sheet Tolerances
Manufacturers produce engineering plastics that are slightly oversize in either diameter and/or thickness.
This oversize tolerance, which is listed in the tables below, is provided to assist customers to produce very accurate items within the size shown and remove any minor surface imperfection.

PVC Sheet
Product Information
Product Full Identity:
Unplasticised Polyvinyl Chloride
U-PVC is rated self-extinguishing, has excellent chemical resistance with high mechanical and tensile strength, together with a high degree of stability. U-PVC is easily
weldable but has a limited operating temperature range of 0°C to +60°C.
PVC sheet has good hardness and mechanical properties
Good electrical insulating properties
Very high chemical & moisture resistance
Excellent forming characteristics
Good dimensional stability
Bondable and an excellent for welding
Self-extinguishing
Fairly inexpensive
The heat stability of PVC isn’t great– when the temperature reaches 140 °C PVC starts to decompose and its melting temperature is 160 °C
PVC is an engineering plastic with good insulation properties but its electrical insulating property aren’t quite as good as plastics such as polyethylene and polypropylene
It’s generally only suitable for medium or low voltage and low frequency insulation materials
Most products made with PVC are long lasting – up to and over 60 years. Because of this reliability throughout their service lives, maintenance or repair is reduced significantly. It is the most widely used plastic in building and construction applications. PVC is resistant to oxidation and degradation and its inherent chlorine content gives it excellent fire resistance.
PVC sheet should not be used for components that need very high wear resistance or will come into continuous contact with food products or maybe items requiring a lot of flexibility, low friction, or high temperature resistance.
PVC is quite hard and machines pretty well leaving a nice machined finish. If possible use double edged milling cutters. When sawing using a circular saw, use saw blades with hard metal-inserted teeth and a tooth spacing of 10 to 20 mm as this has been found to be especially effective.
Gluing PVC is pretty easy and there are quite a few compatible adhesives. Solvent cements and contact adhesives all work fine as does super glue. High frequency welding (gluing) is possible.
PVC sheet exhibits mediocre resistance to wear and abrasion in comparison to Nylon and UHMWPE. PVC is pretty tough though although becomes more brittle as the temperature falls below zero.
In general, PVC is suitable to withstand most strong acids, alkalis, aqueous solutions that are not strongly oxidising, aliphatic hydro carbons, fluorides, photographic and plating solutions, brine, mineral oils, fats and alcohols. However it should not normally be used with aldehydes and ketones, ethers, cyclic ethers, esters and aromatic and chlorinated hydrocarbons, nitro compounds, some petrol / benzene mixtures and similar solvents which lead to a marked swelling and softening of the material.
PVC pipes have been analyzed after in-ground use for over 35 years and have shown no detectable corrosion or degradation and have been estimated to possess an additional 50 years of service life.
PVC sheet is an extremely durable material that is much stronger than some other plastics. It can typically withstand impacts many times that which completely shatter components made of Acrylic or Styrene, for example. PVC is extremely chemical resistant and resists attack or degradation from a wide range of chemicals, making it the material of choice in many tough industrial applications.
PVC sheet is a durable, tough material that is resistant to chemicals, acids, weather and abrasion. It can be machined and tooled into a vast variety of shapes and components. It is strong yet relatively lightweight, affordable and widely available. While it has a low melting point in comparison to other plastics, this is a great advantage to fabricators. It has a very good fire rating as its self extinguishing.
