pvc wall sheet for sale PMMA

I. PVC  Introduction

PVC  is  made  up  from polyvinyl chloride  which is the  most  widely  used  among all  ethylene.This  kind   of   plastic  is  renowned  for  impressive  hardness  and mechanical  strength.However,its mechanical  strength   will be  enhanced  by increasing molecular  weight,and will be  lowered  by  increasing temperature.

CPVC(chlorinated polyvinyl  chloride) is  a  new kind  of  industrial  plastic  produced  by  chlorination  of  polyvinylchloride  resin.During this process,molecular structure  of  PVC  is  amplified  in  terms  of irregularity and chemical polarity,resulting in more  prominent solubility  and  chemical  resistance  to heat,acids,alkalis,salts and axidizing agents,etc.

Furthermore,compared with  PVC  sheet  and  rod,CPVC sheet has  more  chlorine  content  which  is increased from 61.7% to the range of 72 to 75%.Meanwhile,Vicat softening point  is promoted  from  the range of 60℃ to 72℃ to the range of 85℃ to 90℃.The  working temperature for long-term use exceeds 85℃.

II. PVC   Strength :

1.Outstanding   mechanical   strength  and  stiffness.

2. Good  electrical  insulation  and  flame retardancy.

3. Easy to  weld and print.

4. No water  absorption and no deformation.

5. Ultraviolet-proof.

6. Excellent  chemical and corrosion  resistance.

III. PVC  Applications

1.Pollution  handling    equipment.

2.Equipment  for  electroplating and  chemical   processing.

3.Manufacture  equipment   for   semi-conductor.

4.Maching  parts  and  base  plate.

5.Scrubber ,kitchen ventilator  and  other   protective    devices.

6.Packaging  for  food,medicine  and    cosmetics.

7.Injection molded   products  such  as  pipes,valves, housing  for   office  supplies and electroinc  products. 

I. PMMA Introduction

PMMA,also called acrylic,is a kind of colorless and transparent particle. It provides good transparency,chemical stability and weathering resistance.And easy to stain, easy  processing.Besides,it has beautiful appearance.It's widely used in the modern construction industry.PMMA is a non-toxic and envirnmentally friendly material that can be used to produce tableware.PMMA generally can be divided into pouring plates,plate and extrusion molding.

II. PMMA  Strength

1. Excellent transparency with a light transmission of 93%

2. High gloss and colorless

3. Good electrical insulation from high electrostatic charges

4. Resistant to weathering conditions

5.High surface hardness

6. Suitable for decorating

7. Real mould ability

8.Good mechanical for polishing

9.Resistant to non-polar solvents(oils, aliphatic hydrocarbons).

10. Suitable for use in contact with food.

Ⅲ. PMMA Application

1.Automobile industry (signal equipment, instrument  panel,etc).

2.Pharmaceutical industry(storage of blood vessels,etc).

3.Industrical applications(DVD,light scattering devices).

4.Electronic products,keys (especially transparent).

5.Daily consumer goods(beverage cups,stationery,etc.)
