Product Description:


Brief description ‍of PVB Interlayer Film:


PVB interlayer  is a macromolecule material molded by polyviny, butyral resin that is plasticized and extruded by plasticity. Our PVB film with excellent light transparency, heat and cold resistance, elasticity, is well-sticking to inorganic glass and the making of laminated safety glass. Usual thickness specification is between 0.2 mm - 2 mm.


Usage of PVB Film:


PVB interlayer is mainly used in making laminated safety glass. Laminated glass is a special glass which is inserted with PVB film between two layers of common glass, which under high heating temperature and pressure, binds to create a single construction. Because of PVB laminated glass with the function of safety, heat preservation, noise proof, and ultraviolet resistance, etc, it is widely used in areas such as high-rise building and auto. PVB film with special formula is also used in airplane, space flight ware, military instrument, solar battery, solar energy acceptor and so on.



PVB Film Features:



The PVB interlayer withstands penetration from impact. Even if the glass cracks, it will only have web-shaped similar fine cracks, and splinters will adhere to the interlayer and not scatter. In such case. it still can be used until it is replaced.

2,Burglary Proof

Since the laminated glass with QIXUE PVB interlayer is very shock resistant, even if a burglar cracks the glass, the laminated glass can still keep its structure integrity because of the middle-layer adherence tenacity. As such, the laminated glass has much strength to resist shock. It also helps reduce outside visibility

3, Structure Integrality

Performance of laminated glass is the Same as single piece glass under the normal load. however once the glass broke up. laminated glass can keep its structure integrality. little shattered glass dropping down.

4, Sound Control

PVB interlayer in laminated safety glass has a resisting effect on sound waves. PVB laminated glass can effectively prevent the spread of noise especially those located in airports, railway stations, and busy streets.

5, Anti-Ultraviolet

PVB interlayer can filter 99 % of the ultraviolet light thereby helping to avoid direct sunlight and delaying the aging and fading of interior decoration to prolong its service life

6, Energy conservation

Laminated safety glass with QIXUE PVB interlayer can provide an outstanding heat-resisting performance and help save energy conscription. When the laminated glass adopts dark PVB interlayer with low-light transmittance, the same thickness has a stronger thermal resistance effect.


Packing of PVB Film:


Every layer Of PVB film roll is separated by PE film and vacuumed by aluminum foil and put into wooden cases. The finished quality-control approved product is enclosed with conformed certification and packing list.



Guarantee period of PVB Film:


Well-stored and under normal temperatU re, the product has a quality guarantee Of 2 year.

Q:What are the factors that affect the barrier property of plastic film?
When the crystallinity is constant, the polarity of macromolecules or strong polar molecules is difficult to diffuse because of the tight combination between molecules. The greater the molecular polarity is, the smaller the permeability of the resin is, the better the gas barrier is. In common plastic resins, PET and PVA are strong polar resins, PA, PVC are polar resins, PS is weak polarity resin, PE and PP are non-polar resins. Their gas resistance increases with the increase of molecular polarity, such as PET and PE, the transmittance of O2 is very different.Water vapor is a polar molecule. According to the principle of similar dissolution, the water vapor in the polar molecular plastics is integrated and diffused faster than non-polar plastic molecules, and its moisture permeability is also larger. High barrier materials and PET molecules have strong polarity, and their moisture permeability is greater than non-polar molecular PE. Therefore, PE is an excellent moisture resistant packaging material.
Q:A concrete cover film, under what circumstances to cover, what does not cover
The thin film is a thin, soft transparent sheet. Made of plastics, adhesives, rubber, or other materials. A scientific interpretation of a polyester film is a 2 dimensional material formed by atoms, molecules, or ions deposited on the surface of a substrate. Example: optical film, composite film, superconducting film, polyester film, nylon film, plastic film and so on. Films are widely used in electronic, electrical, mechanical, printing and other industries.
Q:Will iron make any pollution when it is melted again?
Like the plastic film made of polyethylene, polypropylene, EVA and other plastic is generally non-toxic, widely used in food packaging industry. And PVC plastic plastic film due to the addition of stabilizers containing lead and cadmium, it is harmful to humans, but if the use of PVC non-toxic formula (using non-toxic stabilizer and plasticizer, etc.) made of plastic film can be used for food packaging.
Q:What are the LLDPE plastic films and what are the main uses?
The production of LLDPE begins with transition metal catalysts, especially Ziegler (Ziegler) or PHILPS (Phillips). A new process based on the olefin olefin metal derivative catalyst is another option for LLDPE production. The actual polymerization can be carried out in a solution and gas phase reactor. In general, butene is copolymerized with ethylene in a solution phase reactor, butene. Polymerization of Cyclohexene with ethylene in a gas phase reactor. The LLDPE resin generated in the gas phase reactor is in the form of particles and may be powdered or further processed into pellets for sale.With hexene and octene is based on a new generation of super LLDPE from mobile, union carbide. Novacor and Tao plastics et al. These materials have great toughness limit and have new potential in the application of automatic bag removal.
Q:Rigid plastic film problems
Such as plastic injection molding, the key is the material, too thin is not good and not easy deformation, good exhaust, the glue outlet is not good arrangements, such as the use of good material such as PA46PA66, good quality recommendations can be used about 0.5mm thickness. Other materials can also be tried and try to be a little harder.
Q:Why should a plastic film be added to the new cement road?
The maintenance of concrete, according to the thermal calculation, concrete internal and surface temperature is less than 25 degrees, concrete pouring time after surface covered with a layer of plastic film insulation, timely prevent the conservation of water caused by excessive temperature difference between inside and outside the concrete temperature crack.
Q:Does the plastic film on the bank card fall off and affect the use?
The damage of the plastic film on the front of the bank card does not affect the use of the card. The key is the magnetic stripe on the back of the bank card. If the magnetic stripe is valid, your bank card can be used normally. It doesn't matter.
Q:What plastic films can be made into plastic bags?
Aluminum foil can also be added to the composite film in the middle, play a barrier role.With regard to composite membrane bags, you go to the PP forum, where many people in the industry know very well
Q:Is plastic film made of turning? Is the machine expensive?
The unit is based on the above situation, all countries in the world according to relevant data, combined with years of production experience of our company, the company engineers carefully designed, through repeated selection, trial production of new product success, by many users, this unit has wide adaptability, low pressure, high pressure, can be blown linear low density three a polyethylene film, not only for their new film blowing, recycled plastic blown film, is also suitable for their stable performance, reliable quality, it is a multifunctional molding unit in China is more advanced at present.
Q:Plastic film surface corona treatment, the bigger the betters?
The surface tension requirement of the general printing processing film is 38 42dyn; the surface tension of the composite processing film is required to reach 42 -54dyn; the surface tension of the film processed by vacuum aluminizing is not less than 42 50dyn.
