Brief introduction of PVC formwork for concrete:

A new formwork material, new type of plastic formwork

PVC formwork for concrete is a new type of plastic formwork product, which is made of Virgin & Pure UPVC only. 

Compared with traditional wood/plywood formwork materials, the biggest advantage is that it can be reused for at least 50 times in plain wooden structures, and much more times in metal frames which offer good protection to formwork sheets.

Compared with steel/aluminum formworks, its advantage is that it's lightweight and is flexible to cut into any dimensions. 

PVC formwork for concrete was created by over 10 years ago under the worldwide hot trend of "replacing wood with plastic", is a good choice to substitute traditional formwork materials, and can greatly save the forest sources. Recently several years, it's being well-known by tens of countries.

Essential parameters of PVC formwork for concrete:

Similar to regular plywood/wood formworks, the popular sizes of PVC formwork for concrete are similar 4'x8'x12/15/18mm. 

Details as following:

Decorative applications of PVC formwork for concrete

JINGFANG® PVC plastic formwork can be laminated with veneers, and then applied to decorations and furniture.

Raw material of PVC formwork for concrete: Virgin & Pure UPVC

Since 10+ years ago, UPVC has been proved to be the most qualified and the optimal raw material selection for PVC formwork. This is a well-known point in this industry by almost manufacturers.

UPVC, the full name is Unplasticized Polyvinyl Chloride, is also named Plastic Steel, or PVC-U.  It is the upgrading of general PVC that removes plasticizers to achieve better engineering properties, so as to retain the rigid chain structure, and increase the strength.

It strictly adheres to the "Three-No-addition" principle: no plasticizers, no heavy metal stabilizers, no calcium carbonate fillers. Therefore, it 's environmental friendly, corrosion resistant, formaldehyde-free, has excellent UV resistance performance and outdoor ageing resistance.

Shandong Jingfang Import and Export Co., Ltd. is the only factory who persistly adopt "Virgin & Pure UPVC" as the solo main raw material to manufacture PVC formwork for concrete all along.

We adopt "Virgin & Pure UPVC" as the solo main raw material, which accounts for more than 95% (the rest 4~5% is for necessary additives), never add any recycled PVC/PP/ABS materials, so can guarantee the  qualified strength, elasticity modulus and UV-resistance of JINGFANG® PVC formwork for concrete, thoroughly solve the deformation/cracking /bending problems of unqualified PVC formwork for concretes.

Compared with general PVC, UPVC has the following advantages:

1. Higher strength.

2. Better UV resistance and temperature resistance.

3. Environmental, no plasticizers, no heavy metal stabilizers, formaldehyde-free.

4. Higher resin purity.

5. Over 4 times better outdoor anti-aging performance than general PVC.

Except UPVC, there are other different plastic formwork materials in the markets, including general PVC, recycled PP/ABS, etc. 

Such materials are mainly recycled from the following 4 uncontrollable sources: 

01. Labels for beverage bottles.  

02. Wasted PVC/PP plastic materials.

03. Temporary rain pipe.    

04. Unqualified used formworks.

Advantages of PVC formwork for concrete:

1. Reuse 50+ times, saving much cost

JINGFANG® PVC formwork for concrete can be reused ≥50 times in plain wooden structures (left photo),  and much more times in premium metal structures. This means the lifespan of 1 piece of JINGFANG® PVC formwork for concrete equals to ≥ 5~10 pieces of plywood formwork.

2. Same sizes & applications as plywood formwork 

JINGFANG® PVC formwork for concrete has the same sizes and applications as conventional plywood formwork, including for wall, slab, column, stairs, tunnel, bridge, etc. 

Its usage in preparing, handling, installation and assembly are same as using plywood formwork. No changes to the formwork structure and construction process.

3. No special tools and trainings required

JINGFANG® PVC formwork for concrete has excellent screw holding strength, can be freely saw, cut, drill, nail, and shaped into any sizes as desired.  

Workers may prepare the JINGFANG® PVC formwork for concrete as the same way that they use conventional plywood formwork. 

No additional trainings or special tools required for workers to handle the product.

4. Never delaminates

JINGFANG® PVC formwork for concrete adopts the foaming technology, not layerinng or laminating. It will never delaminate even after reusing 50+ times. 

So it can be reused continually unless it is badly cracked by violent construction (such as throwing hardly frequently)

5. Smooth concrete surface

Our mirror surface technology ensures JINGFANG® PVC formwork for concretesmooth surface, and is able to maintain its smoothness even after reusing for 50+ times. 

This helps ensuring all the wall surface in uniform smoothness across first to top floor.

6. High Load-bearing Capacity

JINGFANG® PVC formwork for concrete has good surface hardness with excellent strength in during high impact. This is another important reason why it can be reused 50+ times in a plain wood support structure.  

7. High Bending Strength and Elasticity 

JINGFANG® PVC formwork for concrete has excellent bending strength. You can curve it freely in your round formwork structure.

Even in winter, JINGFANG® PVC formwork for concretemaintains its elasticity in bending. Non-fragile.

8. Antiflaming

With pure UPVC as the only main material which accounts for over 95%, JINGFANG® PVC formwork for concrete is anti-flaming without hidden safety hazards. 

This effectively reduces the fire risk and limits the spread of fire.

9. Weatherproof, UV resistant, Chemical Resistant Against Harsh Environment

JINGFANG® PVC formwork for concrete is 100% waterproof, UV resistant, chemical/acid/alkali resistant.

So it is durable enough to be used, stored or placed at outdoor environment without the need of any protection, including under the weather of raining, snowy, in Summer, or in Winter.

10. High Temperature Resistant and Freezing-thawing Resistant

JINGFANG® PVC formwork for concrete has good resistance against temperature. 

It shows no shrinkage, bulge, cracking or any sign of deformation under -25℃ to +70℃. Actually, it can hold 200+℃, which is the temperature of  the manufacturing process.

Non-fragile in Winter. You can put it outside without special curing in snowy weather. 

11. No Need Releasing Oil, Easily Releasing and Cleaning 

With sustaining smooth surface and excellent hardness, JINGFANG® PVC formwork for concrete doesn't stick concrete stubbornly, which ensures it to be easily cleaned with water+mop.

No releasing agent or oil is required before and during concrete demoulding process. Easily cleaning.

Easily demoulded by hands, leaving the wall surface smooth and glossy without the need of secondary plastering.

12. Recyclable with Extra Returns

UPVC is one of the most popular plastic materials in the world. It is easy to resell the used JINGFANG® PVC formwork for concrete to related plastic industries, with higher returns than used plywood formwork. Such as PVC tubes, plastic furniture, cabinet, box, etc.

For full sizes, you can reuse them continually or rent out to other projects;

For small parts, you can can re-sell them to related industries. 

13. Environment friendly

JINGFANG® PVC formwork for concrete is made of UPVC material only, never add any wood powder. It adopts foaming technology, not layer or laminated, no any glue is used in manufacturing. 

So it is environment friendly, doesn't discharge any infectant or toxic gas. It is in accordance with environmental trend of the earth.
