    Silicon nitride ceramic bulletproof tablets

    Bulletproof tablets are made of super hard silicon nitride materials with same color and size, having moderate density and high bulletproof ability.
    All kinds of bulletproof tablet meet the NIJ, European, Chinese standards, pass the test of authorities. Our ceramic bulletproof tablets have the following characteristics: good performance, light, big protective area,less striking distance, effectively prevent bullet penetration. Meanwhile,it can avoid or significantly reduce the penetrated damage to human body.
    ceramic bulletproof tablets can be made into protective armor for cars and planes to deliver better performance, especially against APHE has a better effect.
