Centrifugal Glassfiber

Fully retain the original length of the glass fiber and the horizontal configuration of the centrifugal glassfiber in the length direction. Compared with the ordinary centrifugal fiber with disordered fiber configuration, the fiber has a longer path for heat transfer, Thus achieved lower thermal conductivity. Zisun Technology,our strategic partner, is the sole bio glassfiber company in China certified by Germany Fraunhofer and complies with the EU Note Q standard.

Ordinary Fiber Configuration

The fiber distribution is uneven, the configuration is disorganized, there are more vertical fibers, and the heat transfer is faster.

High Performance Fiber Configuration

The fibers are evenly distributed, the configuration are laid out horizontally, the vertical fibers are less, and the heat transfer is slower.

Core Technology

Independently develop new dry process ultra-fine glass fiber technology to gradually replace traditional wet-process and hot-press dry process. Compared with traditional wet process, the thermal conductivity is lower. compared with traditional dry process, the surface is much more flat. Meanwhile, it has the characteristics of thickness controllable, low cost and stable thermal conductivity.

Develop high-performance fumed silica VIP to respond to diversified markets at home and abroad. Since the distance between silica particles is only about 10 nanometers, which is smaller than the distance required for mutual heat transfer between air molecules, the VIP made of fumed silica is not sensitive to internal air pressure and has long-term and efficient heat preservation performance.
Develop hot-press chopped glass fiber for external wall insulation in the construction market. While having low thermal conductivity, it also has low compression ratio and air leakage expansion rate, and is an excellent thermal insulation material for building exterior wall insulation.
Develop high-performance VIP with the thermal conductivity lower than 1.5mw/mk, improve the energy efficiency class of refrigerators and other home appliances, and have been promoted and mass-produced in customers.

Barrier Film Technology

High-barrier film is the important materials of VIP products, which plays the role of blocking moisture and sealing packaging. Made of multi-layer nano-evaporation/polymerization film, it has extremely low water vapor transmission rate(MVTR) and oxygen transmission rate(OTR), which are the key factors to maintain low vacuum and low thermal conductivity inside VIP.
We independently developed nano-scale high-barrier film materials and nano-scale aluminum-free transparent high-barrier film materials successfully. Compared with ordinary metalized films, the growth trend of accelerated aging tests has been significantly improved.

Getter Technology

Getter is one of the key materials of VIP. Over time, external water vapor gradually penetrates into VIP, causing pressure changes and increasing of thermal conductivity. The role of the getter is to absorb the infiltrated water vapor and maintain the low vacuum and low thermal conductivity of the product. The getter has the ability to absorb water vapor efficiently, which plays a vital role in the life of VIP.
We independently developed high efficiency getter, which is currently the most efficient getter and is indispensable when customers have high requirements for the long-term life of VIP.
