3. Density of sponge: low, medium, high,super high
4. Grit: P36-40-46-60-80-100-120-150-180-240
1 excellent polishing
2 self-sharpness and water-resistant
3 high tensile and high bend strength
4 high elasticity
Aluminum oxide, Silicon carbide, Foam.
Low density ,foam is flexible
Mainly used for solid wood door industry, technology character, stainless steel, paint surface repair grinding, etc
It can save time and improve the effort ,can handle injection molding product surface scratches, burrs, and polishing. And for different products but also arbitrary curve grinding with ease, do not worry about some curved surface is not be polished.
Grinding block is based on foam or EVA , is flexible and soft ,with the sand on surface , the product not only have the super grinding effect , also has elastic , will not hurt the hand . Itself has the function of water storage ,so can improve efficiency ,and it’s very convenient to use ,can be used for both wet and dry , for all kinds of metal and wood.
