Flame Retardant Masterbatches (HFFR)
Home »
XINOMER® MB HFFR are halogen-free flame retardant concentrates for the flame retardant finishing of polyolefins. The masterbatches can be added in the injection moulding and extrusion process or processed together with the base compound as a premix.
In addition to meeting fire tests, our masterbatches also allow you to achieve high mechanical properties thanks to the active carrier system.
Depending on the dosage and masterbach, you can achieve fire requirements such as:
- UL94 VO
- UL94 V2
- Glow wire test850°C
- UL94 HB
Typical applications include housings, boxes, containers, baskets, covers, linings, foils and blown bodies.
XINOMER HFFR Masterbatches
With our halogen-free, flame-retardant batch solutions (XINOMER MB HFFR), you can give your polymer products a flame-retardant finish.
- XINOMER MB HFFR grades can be used to selectively flame retard polypropylene and polyethylene. It can alsobe used to increase the flame retardancy of halogen-free, flame retardant thermoplastic compounds at low addition levels (approx. 1 to 6 wt.%).
- XINOMER MB HFFR products are halogen-free flame retardant concentrates, based on phosphorus / nitrogen (absolutely free of halogens and heavy metals).
- Thanks to our optimised carrier systems, there is only a slight impact on the other material properties such as strength, elongation at break, modulus of elasticity, etc.
- They can be processed with the usual processing techniques.

Where are the advantages of masterbatches
Universally applicable
Batches can be used universally within the same polymer family. For example, if a processor has several polymers in use for HFFR components, he can use one and the same batch for certain properties. For certain applications, compounds are “overengineered”. The batch proportion, however, can be flexibly adjusted by the processor. By setting the necessary flame retardant content via batch, he can use only as much flame retardant as is necessary or prescribed by the standard. On the one hand, this saves costs, since flame retardants are more expensive than base polymers. On the other hand, it leads to better mechanical properties, because the more flame retardant is added, the worse the mechanical properties are.
Individually dosable
It is not uncommon for a processor to have to produce plastic components in different geometries, such as different wall thicknesses, but at the same time achieve the same fire class for all parts, for example V0. Here he can make use of the fire tests. Based on these tests, he can set the exact batch dosage for each of his components. This increases his cost efficiency. Certain batches are also used as “boosters”. In this case, an HFFR compound is already present, with which some components just fail the fire test. This can happen with a portfolio of different components with different geometries, especially with thin-walled parts. By adding a few percent booster batch, the components in question then pass the test.
Cost-effective
Batches are often a more cost-efficient alternative to compounds. It is true that batches are more cost-intensive to purchase than compounds due to the high load of expensive flame retardants. But since they are mixed with cost-efficient standard polymers such as PE or PP during processing, this results in a lower price per kilo than a comparable compound.
Our aim is to provide our customers with quick solutions to their challenges and to meet customer requirements as an efficient and flexible material supplier.
