How does tert-butyl peroxy maleate affect workers’ health?
Apr
Tert-butyl peroxy maleate (C8H12O5) is an important chemical in industrial production, but it carries potential risks to workers’ health. This article explores its effects on human health and the necessary protective measures in factories using this chemical.
1. What is Tert-butyl peroxy maleate?
Tert-butyl peroxy maleate (C8H12O5) is an organic compound in the peroxyester group, mainly used in the plastics and rubber industries. Its molecular structure contains a peroxy group (-O-O-) linked to a maleate group, giving the molecule specific reactive properties.
In industrial applications, Tert-butyl peroxy maleate acts as an initiator for polymerization, triggering cross-linking reactions between polymer chains and improving the mechanical and thermal properties of materials. It is also used in producing composite materials, coatings, and technical rubber products.
Due to its instability and ability to generate free radicals, careful handling is required. Direct contact or inhalation of its vapors can cause adverse health effects, especially for workers in factories where the chemical is used. Understanding its properties and applications not only enhances production efficiency but also ensures workplace safety.

2. Sources of Tert-butyl peroxy maleate in production
In production, this compound is mainly formed through reactions between free-radical initiators and unsaturated monomers such as styrene or acrylic compounds. These reactions are conducted under controlled temperature and pressure to ensure safety and efficiency.
Additionally, it can be synthesized directly from precursors like maleic anhydride and peroxy-containing compounds under suitable reaction conditions, using specialized equipment to control heat and pressure and prevent uncontrolled decomposition.
3. Industries using Tert-butyl peroxy maleate
In plastics and rubber manufacturing, Tert-butyl peroxy maleate is used as a polymerization initiator, especially for unsaturated polyester resins and composite materials, enhancing mechanical strength and product durability.
It is also applied in paints and coatings, accelerating chemical reactions to reduce drying time and improve coating longevity, particularly in products exposed to harsh environments.
In composite material production, it helps cure unsaturated polyester at high temperatures, increasing mechanical performance. In rubber manufacturing, it aids in producing synthetic rubber and elastomers, improving mechanical properties and durability.
In summary, Tert-butyl peroxy maleate plays a key role across industries from plastics and rubber to coatings and composites, enabling the creation of high-strength, durable products.
4. Effects on workers’ health
Exposure can cause local irritation such as dermatitis, conjunctivitis, or upper respiratory inflammation. Prolonged or high-concentration exposure may result in tissue damage at contact sites. The compound may also trigger allergic skin reactions, including itching, rash, or contact dermatitis. Its decomposition and free radical generation can further increase the risk of tissue injury and allergic responses if exposure is uncontrolled.
5. Safe exposure levels
Currently, no specific regulatory limits for Tert-butyl peroxy maleate exposure exist in Vietnam. Therefore, safe exposure levels should reference international standards and best industrial practices. 
As a basic principle, following safety standards and minimizing exposure in industrial environments is essential. Organizations such as the U.S. Occupational Safety and Health Administration (OSHA) provide guidance to protect workers from harmful chemical effects.
6. Measures to minimize health risks
To reduce health risks, strict preventive measures should be implemented, following the hierarchy: elimination, substitution, engineering controls, personal protective equipment (PPE), and training.
Key actions include:
Ensuring adequate ventilation in production areas to lower airborne concentrations.
Using PPE such as respirators, gloves, protective eyewear, and clothing to prevent direct contact.
Providing regular training on chemical hazards, correct PPE use, safe handling, and emergency procedures.
Periodically monitoring workplace air for chemical concentrations and taking steps to reduce exposure levels, preventing occupational diseases.
Occupational Safety Training ensures workers understand hazards and comply with safety protocols.
Regular workplace environmental monitoring collects and analyzes harmful factors to adjust and minimize risks, helping prevent occupational diseases.
