use Octabromodiphenyl ethane (ODOPE) and Sb2O3, and add expandable graphite (EG) to produce flame retardant LGFPP.
flame retardant LGFPP formulations
Engineering plastics can be modified by physical, chemical or physical and chemical methods, including blending (alloying), copolymerization (grafting) and filling reinforcement.
PP/PE toughening system The toughening effect of LDPE on PP is obvious, but other mechanical properties such as flexural modulus decrease rapidly. When the content of HDPE in PP is less than 10%, it has a rigid toughening effect on PP, that is, while increasing the impact property, other mechanical
Design Examples of Inorganic Rigid Particles Toughening Formula : PP + calcium carbonate/ kaolin/ Precipitation BaSO4/ Nanofiller/ Alkali earth metal salt.
Matters needing attention in the design of toughening formula:
1.The compatibility between elastomer and resin should be good.
3. Synergistic effect of elastomer
4. Other factors to be considered
5. Rigidity compensation
Rigid PVC/EVA blends can be used to produce plates and profiles, or to produce low-foamed products.
Soft PVC/EVA blends can be used in the production of cold resistant film, sheet, artificial leather, and also used in the production of foaming products.
