1、Safety Data Sheet: Phenolic resins

Remove victim out of the danger area. Keep affected person warm, still and covered. Take off immediately all contaminated clothing. In all cases of doubt, or when symptoms persist, seek medic-al advice. In case of unconsciousness place person in the recovery position. Never give anything by mouth.

2、Formaldehyde

Today, phenolic resins are polymers still widely used, with a global production of about 12 million tons/per year. However, their syntheses need the use of formaldehyde and phenol, which are highly toxic. Notably, formaldehyde is carcinogenic.

3、Chemical characterization and phytotoxicity assay of Novolac phenolic

Abstract Novolac phenolic foam resin (NPFR), a polymer of phenol and formaldehyde, is used in healthcare to ensure thermal stability of cold chain products. Post-use, NPFR is classified as non-hazardous solid waste and disposed of in landfills without prior treatment.

4、A comprehensive review on modified phenolic resin composites for

Current research on PR modification emphasizes both physical methods, including filler enhancement and fiber reinforcement, and chemical methods, such as copolymerization, grafting, and cross-linking.

5、is phenolic resin toxic

While phenolic resin contains potentially harmful substances like phenol and formaldehyde, the risks are significantly mitigated when the resin is fully cured and handled properly. The greatest risks occur during the manufacturing process, where exposure to the raw chemicals is higher.

Is Phenolic Resin Toxic? Safe Lab Material Guide

In this guide, we’ll clarify what makes phenolic safe (or not), how it compares to epoxy resin, and what lab managers should know before installing or modifying resin-based components.

Comparison of the properties of phenolic resin synthesized from

Different PG and PPF resins were prepared using different amounts of glyoxal and paraformaldehyde and compared with conventional PF resins. These results indicated that glyoxal oxidation affected the pH of PG.

Technology of Low

Each of the above types of resins has advantages and disadvantages. The disadvantages of polymers used in woodworking include low water resistance, dark color (for phenolic resins), and increased content of harmful substances.

Phenolic Resins

Phenolic resin identity is hidden and has little consumer recognition or identity. The apparent hidden but security/comfort aspect of phenolic resins is best illustrated by considering the use of phenolic resin as hinder in friction linings or automobile brakes.

Exploring the Toxicity of Modified Phenolic Resins

In the development of modern industry, the application of chemical materials has become increasingly widespread. Among them, modified phenolic resins, as a critical class of thermosetting resins, play a pivotal role in fields such as construction, electronics, and automotive industries. with their broad utilization, concerns about the toxicity of modified phenolic resins have gradually emerged as a focus of public attention.

Modified phenolic resins are thermosetting polymers derived from phenol and formaldehyde, modified by additives such as curing agents and accelerators. They are prized for their excellent heat resistance, electrical insulation, and mechanical properties, which have driven their widespread adoption. their complex chemical composition, which includes various organic solvents and heavy metal salts, poses potential health risks if exposed to them over long periods or in large quantities.

Firstly, organic solvents in modified phenolic resins constitute one of their primary toxic sources. These solvents, including benzene, toluene, and xylene, are not only flammable and explosive but also highly volatile. Prolonged inhalation can irritate and damage the respiratory system, potentially leading to chronic bronchitis, emphysema, or even cancer.

Secondly, modified phenolic resins may contain heavy metal ions such as lead, cadmium, and mercury. These metals can enter the body through skin contact or inhalation, harming the nervous, digestive, and reproductive systems. Long-term exposure may result in symptoms like memory decline, anemia, or impaired liver and kidney function.

Additionally, the production and use of modified phenolic resins may generate other hazardous substances, such as formaldehyde and styrene. Formaldehyde, a strong irritant, can cause respiratory inflammation and eye irritation, while styrene, a known carcinogen, may increase the risk of leukemia with prolonged exposure.

How can we address these toxicity concerns? First, manufacturers must strictly adhere to national regulations and environmental standards, ensuring all raw materials, additives, and catalysts meet safety requirements. Employee training should also be strengthened to raise awareness of potential hazards and prevent accidental mishandling.

For consumers, vigilance is essential when selecting and using modified phenolic resin products. Choose products from reputable sources with environmental certifications, prioritizing low-toxicity or non-toxic options. Follow usage guidelines meticulously to avoid excessive exposure.

Government agencies should enhance regulatory oversight of the industry, enacting stricter environmental and safety standards. Legislative measures to restrict toxic substances and improve overall environmental compliance are crucial.

modified phenolic resins, as indispensable chemical products, demand rigorous attention to safety and environmental impact. Only through collective efforts—by industries, consumers, and regulators—can we maximize their benefits while minimizing harm to human health and the environment.
