SGP Film (Bulletproof Grade)

Product introduction

As the bearing capacity is increased, the deflection is reduced and the glass thickness can be correspondingly reduced. It is possible to reduce the amount of glass by about 40%, which correspondingly reduces the weight of the curtain wall. Not only benefits the main structure design, but also energy saving.

 Product advantages

Chongqing Huakai Plastic Co., Ltd. has become the world's second and the China’s first qualified manufacturer of ionic interlayers.

Our products are produced domestically, compared with imported film
