In general, what are the original PCR sources?

  1. Primary plastic material (Resin) is made from petroleum-refined chemicals into resin, and then through plastic blending process to become plastic particles.
  2. Recycled plastic materials (PCR) are waste from consumers after use, such as: TV frames, refrigerators, washing machines, office equipment, printers, faxes, telephones, car lampshade, water bottle, PC film, PC board, CD/DVD, frame, goggles, safety helmet, etc... After recycling process and blending process to plastic granules.

What is the process of PCR plastics?

The processing procedures of PCR products are as follows:

Recycling → Disassembly → Sorting → Shredding → Cleaning → Compouding → Quality Control

PCR quality control is as follows:

  1. Incoming quality control→process quality control→final process quality control
  2. Various quality assurance equipment to ensure all the performance of plastic
  3. Use Computer color system for color matching
  4. XRF machine control complies with RoHS standard
  5. Stocking number and batch number management

What is PMC (bakelite powder)?

PMC is Phenolic Mounding Compound bakelite powder.

Features of Changchun bakelite:

Plastic antibacterial agent and BPR and EPA certification

In the recent event of COVID-19, antibacterial and antiviral products have become a global necessity. By adding antibacterial & antiviral agent, your coating, textile, film, and plastic related products will pass ISO 18184 and  ISO 21702 antimicrobial test with flying color.

As a reminder, if your finished products are to be exported to EU or NA regions, the antibacterial material on your products need to pass the EU's BPR or NA's EPA certification. Without these certifications, you may be fined heavily or even prison.

About the law:
BPR Certification (EU Biocide Regulations):Implementation and audit started in March 2017.

Antibacterial agents sold to EU countries and claimed to use antibacterial or antifungal products must be authorized by BPR. If the use of antimicrobial agents without BPR authorization in products is prohibited from being sold in the European market, you will face the risk of fines, imprisonment, and/or product removal. Antibacterial agents that comply with EU BPR authorization can be found in the European Chemical Agency (ECHA) 95 List.

The penalties for EU countries are set by their government agencies, and currently the heaviest penalties are Germany and France.
Germany imposes fines of 2 million to 10 million euros or imprisonment for less than 5 years for violations of the ban.
(refer to Articles 26 and 27 of the Chemicals Act)
France imposes fines ranging from € 7,500 to € 75,000 or imprisonment from 6 months to 2 years for violations of the ban.
(refer to the French Environmental Code (Environmental Code Articles L522-15 and L522-16)).

EPA certification (US Environmental Protection Agency):
Products that claim to be antimicrobial cannot be sold in the United States if the antimicrobial agent used has not passed EPA certification. Otherwise, they will be fined heavily and ordered to be removed from the United States within 3 months.

At present, our antibacterial agent used in plastics has passed BPR and EPA certification, and it has been registered in the European Chemical Agency (ECHA) 95 List. Please use it with peace of mind.
