Japan implemented the container recycling law in April 2000. In 2001, PET bottles were recovered to 170,000 tons, which only reached 40% of the recycling rate. For the PET recycling technology problems. The company successfully developed and produced recycled PET modifiers "AR-P-1000" and "AR-P-1100" from the Japanese company Kasei Chemicals Co., Ltd. and introduced them to the market.
The main characteristics of "AR-P"'s recycling regeneration modifier are: 1 It does not require drying when used. 2 It is very stable at room temperature. 3 It is suitable for all plastic molding processing equipment. 4 It can be colored arbitrarily. The blending is added.6 The impact strength of PET recycled recycled materials is improved.Because AR-P is dispersed in the fine state in the recycled PET molding material, the interfacial tension is small under the action of the forming processing shear force."AR- The ratio of P" to the recycled PET molding material is 1 and the dispersion is good, improving the impact strength of the recycled PET molding material. For example, when 5% "AR-P" is added, the notched impact strength is increased from 2 KJ/mz to 5.5 KJ/ M2。 At a temperature of 10°C, the impact strength at low temperature increases from 1.BkJ/mz to SkJlm2o7. The viscosity of recycled PET molding materials is improved, the flow properties of PET melt molding materials are improved, and the shape suitable for molding and processing is complicated. Shaped products.
