What is the difference between PVC and polypropylene canvas?
PVC is the most common plastic used in book covering materials, and has been used for many years. Polypropylene has become more common recently. Both of these plastics have different handling characteristics. PVC is generally considered to be easier to fold and to conform to the shape of a book more readily, while polypropylene is usually a little more rigid. Sometimes PVC will stick to itself, particularly in warmer weather. Polypropylene is well known for it's non stick characteristics, in fact it is difficult to glue and even permanent marker can be removed from it, giving it superior life and resistance to damage and marking. Polypropylene is also acid free, and is considered to be an archival plastic. PVC is known to have a low level of acidity. PVC is cheaper than PP.
What is the Tg for PVC?

What is SR PVC?

Does hcl acid react with PVC?
Depends on what king of PVC and what's the concentration of the acid. For example the 35% HCl damages the flexible PVC on 50°C, but the rigid PVC not... (The flexible PVC become rigid I think.)
What is Tg?
In chemistry, Tg is the glass transition temperature of an amorphous polymer. It is the individual polymer's fixed temperature at which point it either becomes flexible when the actual temperature of it is higher than the Tg, or it becomes rigid, when the actual temperature is lower than its Tg. An amorphous polymer is one whose structure is tangled. Tg is the cause of polymer items breaking. Leave a plastic bucket outside in winter and it can easily break in its rigid state, frozen or not.

Is PE-wax used for making PVC Resins?

Why does UPVC not degrade?
UPVC is unplasticised, rigid, PVC. PVC resin must be compounded with various additives to make it a useful product. Heat stabilisers, pigments, lubricants,process aids, impact modifiers and fillers are all added to the raw PVC resin to allow it to be processed into a durable product. If a liquid plasticiser is added to the PVC compound the finished PVC product becomes flexible, ie, no longer rigid.
Is PVC and polyethylene the same thing?
They are similar but different. PVC is stronger & more rigid than polyethlene and is used for wastelines & polyethylene is used for water lines.
What is rigid PVC?
P.V.C is an acronym for PolyVinyl Chloride. In everyman tems: Plastic. Rigid PVC is hardened plastic. It is used to make everyday items... the casing for your TV or Hi-Fi etc. P.V.C that does not contain this hardener is variously used in upholstery and clothing among other things.
What rigid substrates wonn't crack?

Can you glue laminate to rigid PVC?
Yes, you can. If possible, first prime the PVC with 'purple primer' ( from plumbing supply store) then use PL200 to join the pieces. Clamp them for 3-4 hours for a strong joint.
