Abstract:
An inorganic filler coated with molybdenum compound used as an additive is added into a resin mixture in an amount of 20 to 80 wt % of the resin mixture, resulted in that printed circuit boards if made from a laminate or a prepreg containing the resin mixture have properties of a low coefficient of thermal expansion, good heat tolerance and excellent drilling processability.
Abstract:
A polypropylene composition provided with lightweight, highly tough and highly rigid as well as having a specific weight of 1.0-1.05 is made of a polypropylene resin, inorganic powder, a toughener, a coupling agent, a compatibilizer and an anti-oxidant; a method of manufacturing the composition involves grafting the inorganic powder onto the polypropylene resin and the coupling agent to form a masterbatch, and mixing the masterbatch with the other additives to enhance bonding ability of the inorganic powder inside the polypropylene composition to endow the composite with good toughness, rigidity and mobility, and reducing undesirable dust.
Abstract:
A modified polyester resin composition comprises a combination of a PET polyester, a PCT polyester, a CHDM modified copolyester comprising PCTA, PCTG or PETG, and a modified polymer at least comprising TPU or EPDM, wherein the modified polymer accounts for 3-25 wt % and the rest accounts for 97-75 wt %, based on the total weight of the resin; and the modified polyester resin composition is suited for use in a halogen-free, heavy metal-free, and volatile organic compound-free polyester-based plastic floor tile excellent in higher resistance to wear and tear, better tensile strength, more preferable resistance to both lit cigarette e and solvents, and particularly being friendliness to environment and not hazardous to health.
Abstract:
A peelable protective film having perfect adhesion for providing temporary protection to objects is disclosed, which protective film having a peel strength ranging between 35 and 100 g/cm is capable of being easily peeled off from an adhered object and without leaving any residual adhesive; a composition containing a vinyl chloride-vinyl acetate copolymer, a high-molecular-weight emulsified, polymerized PVC powder, a low-molecular-weight emulsified, polymerized PVC powder, a trimellitate plasticizer, a diisobutyrate-based plasticizer, a phenol-free Ca—Zn stabilizer, fumed silica, aluminum hydroxide, barium sulfate and calcium carbonate is so suited for making the peelable protective film having a thixotropic index ranging between 2.00 and 2.20.
