Benzoyl Peroxide (BPO), identified by its CAS number 94-36-0, stands as a cornerstone organic peroxide within the chemical industry. As a fundamental raw material, it plays a critical role in various industrial processes, primarily functioning as a highly effective initiator for free radical polymerization. Its chemical formula is C14H10O4. Industrially, BPO is often supplied in a wetted form, typically containing around 75% active ingredient with water, which significantly enhances its safety profile by reducing sensitivity to shock and friction, mitigating the inherent risks associated with transporting and handling dry, pure organic peroxides.

The physical appearance of industrial grade Benzoyl Peroxide is commonly that of a white powder or granule. Beyond its assay, critical quality parameters include limits on water content, chloridion levels, and free acid concentration (measured as benzoic acid), all of which are essential for ensuring consistent performance in sensitive chemical reactions. Understanding its thermal stability is also paramount; key data points such as the Self-Accelerating Decomposition Temperature (SADT) and various half-life temperatures (e.g., 0.1hr half-life at 131°C, 1hr half-life at 92°C, 10hr half-life at 73°C) are vital for safe storage, handling, and processing. These values dictate the conditions under which BPO can be stored and transported without initiating uncontrolled, potentially hazardous decomposition.

One of the primary applications of Benzoyl Peroxide is its use as a polymerization initiator. In this role, it generates free radicals upon thermal decomposition, which then trigger the chain reaction necessary to convert monomers into polymers. This is particularly important in the production of polyvinyl chloride (PVC), a widely used plastic in construction, pipes, and many other durable goods. BPO is also the initiator of choice for curing unsaturated polyester resins, which are foundational materials in composites used in boat hulls, fiberglass products, and coatings. Furthermore, it is extensively employed in the polymerization of various acrylates, leading to the production of paints, adhesives, and coatings with specific performance characteristics.

In addition to its initiating role in polymerization, Benzoyl Peroxide serves other significant functions. It acts as a cross-linking agent for certain polymers, such as polyethylene, enhancing their mechanical strength and thermal properties. It is also utilized as a vulcanizing agent in the rubber industry, facilitating the process that improves the elasticity and durability of rubber products. These diverse applications highlight the versatility of BPO as a reactive organic chemical intermediate essential for manufacturing a wide array of materials that underpin modern industries.

The industrial significance of Benzoyl Peroxide as a raw material cannot be overstated. It is a key upstream chemical ingredient without which the large-scale production of many essential polymers and composites would be challenging or impossible. Its consistent quality and reliable supply are therefore critical factors for manufacturers downstream in the chemical value chain. The global demand for BPO is closely tied to the health of sectors like construction, automotive, and infrastructure, all of which rely heavily on the materials its use enables.

Ensuring the supply of high-quality Benzoyl Peroxide requires expertise in manufacturing and handling organic peroxides safely. Suppliers must adhere to stringent safety standards in production, packaging, and logistics due to the inherent reactive nature of the substance. The transportation of BPO, particularly in its wetted forms, necessitates compliance with international regulations governing hazardous materials to prevent incidents.

As a crucial chemical raw material, the availability and performance of Benzoyl Peroxide directly impact the efficiency and quality of countless manufacturing processes. Manufacturers seeking this essential initiator look for partners who can guarantee purity, consistency, and reliable delivery. The global market for BPO involves a network of producers and distributors serving diverse industrial needs, from bulk polymer production to specialized resin curing applications.

For companies needing to source this vital chemical, understanding the market dynamics and supplier capabilities is key. The price of Benzoyl Peroxide can fluctuate based on global supply and demand, raw material costs, purity levels, and order volume. Buyers often evaluate multiple factors beyond just the price per kilogram, including packaging options (like the standard 20kg cartons mentioned in the source), minimum order quantities (MOQ), lead times, and the supplier's track record in safety and reliability. The ability to purchase material meeting specific industrial quality requirements is paramount.

Securing a consistent supply of industrial grade Benzoyl Peroxide CAS 94-36-0 is fundamental for manufacturers in the polymer and composites sectors. Finding a reputable manufacturer or supplier capable of providing material that meets the required specifications is a critical step in the procurement process. Companies looking to buy Benzoyl Peroxide for polymerization or cross-linking applications must perform due diligence to ensure the product's quality and the supplier's adherence to safety and regulatory standards. Comparing the price offered by different providers is a standard practice, but it should always be balanced against the assurance of consistent product quality and reliable delivery. Establishing a strong relationship with a trusted supplier is key to ensuring a stable and competitive supply chain for this essential raw material necessary for numerous industrial processes.
