Definition of Plastic PVC formwork

Plastic PVC formwork is new type of plastic formwork material, which is made of Virgin & Pure UPVC only. Nowadays, the worldwide trend of environmental protection is being increasing important. 

Under the background of civil engineering worldwide trend "replacing wood with plastic", Plastic PVC formwork was created by 0veru 10 years ago, and got quick development.Recently several years, it's being well-known by tens of countries.

Plastic PVC formwork has same sizes as plywood, can reuse ≥ 50 times, waterproof, anti-flaming, no need releasing oil, UV resistant, etc, is a good choice to substitute the traditional formwork materials including plywood /wood /aluminum /steel /bamboo formworks, so as to greatly save the forest sources.

Basic specifications of Plastic PVC formwork:

Advantages and characteristics of Plastic PVC formwork:

1. Reuse 50+ times, saving much project costs

JINGFANG® PVC plastic Formwork can be reused ≥50 times in plain wooden structures,  and much more times in metal frames. This means the lifespan of 1 piece of JINGFANG® Plastic PVC formwork equals to ≥ 5~10 pieces of plywood formwork.

2. Same dimensions & applications as plywood formworks 

JINGFANG® Plastic PVC formwork has the same dimensions 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 plywood formwork. No changes to the formwork structure and construction process.

3. No need special tools and trainings

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

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

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

4. Uniform foaming technology, never delaminates

JINGFANG® Plastic PVC formwork 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.

5. Smooth concrete surface, guarantee project quality

Our mirror surface technology ensures JINGFANG® Plastic PVC formwork smooth 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® Plastic PVC formwork 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® Plastic PVC formwork has excellent bending strength. You can curve it freely in your round formwork structure.

Even in winter, JINGFANG® Plastic PVC formworkmaintains its elasticity in bending. Non-fragile.

8. Anti-flaming, avoiding hidden safety hazards

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

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

9. Weatherproof and 100% Waterproof

JINGFANG® Plastic PVC formwork is 100% waterproof. So it is durable enough to be used, stored or placed at outdoor environment without the need of any extra protection, including under the weather of raining, snowy, in Summer or Winter.

10. UV resistant, Chemical Resistant Against Harsh Environment

UPVC is the upgrading of general PVC. It has over 4 times better outdoor anti-aging performance than general PVC,  with lifespan for tens of years. It accounts for over 95% in our product formula, so can guarantee JINGFANG® Plastic PVC formwork the qualified resistance against UV, temperatures and weather. 

11. High Temperature Resistant and Freezing-thawing Resistant

JINGFANG® Plastic PVC formwork has good resistance against temperature. No shrinkage, bulge, or deformation under -25℃ to +70℃ . It can be exposed to any weather, raining or snowy, summer or winter. No need to worry about it being weaken by the sunshine or temperature.

12. No Need Releasing Oil, Easily Releasing and Cleaning 

With sustaining smooth surface and excellent hardness, JINGFANG® Plastic PVC formwork 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.

13. 100% Recyclable with Extra Returns

UPVC is one of the most popular plastic materials in the world. It is easy to resell the used JINGFANG® Plastic PVC formwork 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. 

14. Environmental friendly, non-plasticizer, formaldehyde-free

JINGFANG® Plastic PVC formwork 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.

How to install Plastic PVC formwork ?

Tip 01: Edge distance of nailing/screwing 

To prolong the life-span of product, we suggest to leave at least 3-5cm distance from the edge when nailing/screwing on it. 

Tip 02: Beam distance 

In general, we suggest the same beam distances as the plywood formworks which you are using. But, it differs a bit according to the frame structures and concrete thickness. The stronger structures, the shorter beam distance.

Tip 03: Nailing/screwing distance 

Same as the general requirements for all formwork materials, to ensure the average load-bearing capacity of the entire sheet, in addition to the appropriate props distance, we also recommend maintaining an average spacing of nails/screws, such as 30 cm. Especially the corners should be fixed well with nails/screws. Or you can keep the regular way that applied to your structures. 

Tip 04: Joint treatment

If you want to avoid the concrete sticking into the joint, you can paint the joint. The regular painting is workable enough. Some of our clients use the gel coat.

Tip 05:  Repair the holes of nails or bolts 

For the nails holes: normally such holes don’t leak concrete, so not necessary to fix it. If you have strict requirements, you can use glue or wax to cover them. 

For the bolt holes: plastic plug or adhesive tape. Another solution: normally the bolt holes of one single project have same diameters and locations. So some clients cut formworks sheets into small round pieces with 1mm smaller diameter, and then insert them into the bolt holes.

Comparison between PVC formwork and PVC/WPC foam board

There are huge differences between our product and WPC/PVC foam boards. This is a very important point. So detailed explanations are necessary. 

01. Different raw materials and costs.

To save costs, WPC/PVC foam board are manufactured with over 60% or even 80% calcium powder, and much wood powder. Some suppliers even use the recycled PVC. Therefore, WPC/PVC foam board has much lower costs than PVC formwork.

02. Different applications.

WPC/PVC foam board are mainly applied for the fields which don't has strict requirements for strength/nails-hold powder, such as adverting, furniturs, decorations, etc. But it isn't strong enough for construction formworks.

03. Different product performances.

Compared with PVC formwork, WPC/PVC foam board has lower strength/hardness/nail-holding powder/flexibility. It easily gets cracking when applying to shuttering. Therefore, it is not a formwork material. Don't be misleaded.

04. Different machines and manufacturing processes.

It is impossible to manufacture qualified PVC formwork by the WPC/PVC foam board machines: can't get qualified surface crust, density, and strength.

So, if one supplier manufactures both products by the same machine, then there is no doubt that: their PVC formwork is unqualified. Every field has its master.
