for rubber and plastic compound processing. Our additives help in improving the flow properties of compound thereby eliminating shark skin and creating a desirable surface finish to end products without harmful effect on the compound's physical properties. They have excellent release effect resulting in smoother edges as well. As compatibilizer, they increase the shear force without additional load of mixing equipment and improve the dispersion of the compound.

We call our coupling agents as IruBond which stands for IruChem Bonding Agent. They are MAH (Maleic Anhydride) grafted olefins and include

• coupling agents

•  compatibilizers

•  impact modifiers

• tie-layers

IruChem's coupling agents are produced using specially designed extrusion system. These coupling agents are made from our special technology that can eliminate or minimize odor generated during process.  IruBond improves the mechanical properties of olefin compounds containing glass fibers or fillers such as talc, mica, ATH, MDG and other natural materials such as cellulose or wood fibers.   IruBond works well with PP, PE, ABS, nylon, etc.

Phosphorus flame retardants are a class of chemicals used to enhance the fire resistance of various materials. They are increasingly popular due to their effectiveness in fire suppression and their comparatively favorable environmental profile. These retardants are incorporated into or applied to materials to inhibit or resist the spread of fire, making them essential in various industries, including electronics, textiles, and construction.

Effectiveness of Phosphorus Flame Retardants

Phosphorus flame retardants are highly effective in reducing flammability through several mechanisms:

1. Char Formation: When exposed to high temperatures, phosphorus compounds promote the formation of a stable char layer on the material’s surface. This char layer acts as a barrier, protecting the underlying material from heat and oxygen, thereby slowing down combustion.

2. Flame Inhibition: In the gas phase, phosphorus flame retardants can interfere with the chemical reactions that sustain a flame. They release phosphorus-containing radicals that scavenge key reactive species, such as hydrogen and hydroxyl radicals, which are essential for the flame's propagation.

3. Synergistic Effects: Phosphorus compounds often work synergistically with other flame retardants, such as nitrogen-based or halogen-based compounds, enhancing overall fire resistance. For instance, in combination with nitrogen, they can form intumescent systems that expand and form an insulating foam barrier when heated.

Environmental Friendliness of Phosphorus Flame Retardants

Phosphorus flame retardants are considered more environmentally friendly compared to some traditional alternatives, particularly halogenated flame retardants:

1. Low Toxicity and Bioaccumulation: Many phosphorus flame retardants have a lower toxicity profile and are less likely to bioaccumulate in the environment and in living organisms. This reduces their long-term ecological and health impacts.

2. Reduced Release of Toxic Gases: During combustion, phosphorus flame retardants typically produce fewer toxic gases and smoke compared to halogenated flame retardants. This is crucial in improving safety during fires, as smoke inhalation is a leading cause of fire-related fatalities.

3. Regulatory Acceptance: Due to their relatively benign environmental impact, phosphorus flame retardants are more likely to meet stringent regulatory requirements. This makes them a preferred choice in regions with rigorous environmental and health safety standards, such as the European Union and parts of the United States.

4. Biodegradability: Some phosphorus-based flame retardants are designed to be biodegradable, breaking down more readily in the environment. This helps mitigate their impact on ecosystems compared to more persistent chemicals.

Applications

Phosphorus flame retardants are used in a variety of applications:

• Electronics: They are used in the casings and components of electronic devices to prevent fire hazards.

• Textiles: Applied to fabrics to make them less flammable, ensuring safety in clothing, upholstery, and other textile products.

• Construction Materials: Incorporated into building materials like insulation, foams, and coatings to enhance fire resistance.

Magnesium dihydroxide (Mg(OH)₂), also known as magnesium hydroxide, is a widely used flame retardant known for its effectiveness and environmental friendliness. It is utilized in various materials to enhance fire resistance, particularly in plastics, rubber, and textiles.

Effectiveness of Magnesium Dihydroxide Flame Retardant

1. Endothermic Decomposition: Magnesium dihydroxide decomposes endothermically at temperatures above 300°C, absorbing heat and releasing water vapor. This absorption of heat delays the ignition of the material.

2. Dilution of Flammable Gases: The water vapor released during decomposition dilutes flammable gases and cools the material's surface, further inhibiting combustion.

3. Formation of a Protective Layer: The decomposition leaves behind magnesium oxide (MgO), which forms a protective layer on the material's surface. This layer acts as a barrier to heat and oxygen, slowing down the combustion process.

4. Smoke Suppression: Magnesium dihydroxide also helps in reducing smoke production during combustion, which is crucial for improving visibility and reducing toxicity in fire situations.

Environmental Friendliness of Magnesium Dihydroxide Flame Retardant

1. Non-Toxic: Magnesium dihydroxide is non-toxic and does not pose health risks to humans or animals, making it safe for use in various applications, including those involving close human contact.

2. Low Environmental Impact: It is a naturally occurring mineral, and its production and use have minimal environmental impact compared to synthetic flame retardants.

3. No Harmful Byproducts: Unlike halogenated flame retardants, magnesium dihydroxide does not produce harmful byproducts or toxic gases during combustion, enhancing safety and reducing environmental pollution.

4. Recyclability: Materials treated with magnesium dihydroxide can often be recycled more easily, contributing to more sustainable waste management practices.

Wood Plastic Composite (WPC) is a material made from a combination of wood fibers (or wood flour) and thermoplastic polymers. It is engineered to create a versatile, durable, and environmentally friendly alternative to traditional wood products. WPC is used in various applications such as decking, fencing, furniture, and automotive components.

IruChem consults whole steps of the production of WPC.

Composition and Benefits

1. Materials: WPC typically consists of 50-70% wood fibers and 30-50% thermoplastic polymers (like polyethylene, polypropylene, or PVC). Additives such as UV stabilizers, colorants, and coupling agents are also included to enhance performance.

2. Advantages:

   • Durability: Resistant to moisture, rot, and insects, making it suitable for outdoor use.

   • Low Maintenance: Requires less upkeep compared to natural wood.

   • Environmental Friendliness: Utilizes recycled materials and reduces the demand for virgin wood.
