Why Halogenated Flame Retardants Are Still Used in Critical Safety Applications

  Fire safety is one of the most important concerns in industries ranging from electronics to automotive and construction. Over the years, different flame-retardant technologies have been developed to minimize risks, but some continue to dominate specific high-risk applications. Among these, halogenated flame retardants remain widely used despite growing discussions about alternatives. The reason is simple: in critical safety applications where reliability is non-negotiable, these flame retardants consistently deliver unmatched performance. What Are Halogenated Flame Retardants? Halogenated flame retardants are element-based additives like bromine and chlorine. They are added to polymers and other materials to minimize flammability as well as hold back fire. When subjected to fire, they emit halogen radicals that disrupt the chemical reaction involved in the combustion process, thereby slowing down or halting the flames' spread. Their fast action and low concentration capability ...

Slip Additives Masterbatches: Their Role in the Plastic Industry?

 

Slip additives play a crucial role in the plastic manufacturing industry, serving as chemical additives designed to modify the surface properties of plastic products. The primary objective of incorporating slip additives into plastic formulations is to alter the coefficient of friction between the plastic surface and other materials, facilitating a smoother feel and allowing for easier sliding or gliding. 

Here are the key functions and benefits associated with slip additives in the plastic manufacturing process:

Improved Processability:

Slip additives enhance the processability of plastic during manufacturing by mitigating stickiness and improving flow characteristics. This leads to smoother processing, better mold release, and a reduction in production defects.

Surface Lubrication:

Acting as lubricants on plastic surfaces, slip additives decrease friction between the plastic material and other surfaces. This property is particularly beneficial in applications where plastic products come into contact with various materials, such as packaging films or sheets.

Preventing Blocking:

In scenarios where plastic films, sheets, or bags are stacked together, slip additives prevent unwanted adhesion or blocking between plastic surfaces. This is particularly important in flexible packaging applications.

Enhanced Surface Appearance:

Slip additives contribute to an improved appearance of the plastic surface, providing a smoother and more aesthetically pleasing finish.

Anti-scratch Properties:

These additives offer a level of scratch resistance, safeguarding plastic surfaces from minor abrasions.

Improved Handling:

Slip additive masterbatches make it easier to handle plastic products during various stages, including packaging, transportation, and end-use applications.

How Black Masterbatch Enhances Plastic Performance and Durability

  Ever curious about what imparts plastic that rich dark color while also enhancing its overall durability and performance? The secret lies in a specific additive known as black masterbatch. This material is a force to be reckoned with—doing far more than simply color plastic, it boosts its physical properties, enhances UV resistance, and enhances end product durability. Let's see how black masterbatch helps in plastic performance and why it's the first choice among a broad variety of industries. What is Black Masterbatch? Black masterbatch is a concentrated mixture of carbon black pigment blended with a carrier resin and additives. This blend is applied during the process of manufacturing plastic to impart black color as well as improve the performance properties of plastic products. The dense load of carbon black not only guarantees deep colour but also increases resistance to weathering. Black masterbatch can be formulated to be used in different polymers such as PE, PP, P...
