BMC made of jute fiber, cotton fiber or sisal fiber

Lorenz kunststofftechnik has developed a fire-proof, sprayable and eco-friendly mass molding compound (BMC) made of natural fiber reinforced materials, which has lower production costs, helps protect the environment and reduce carbon footprint

fiber reinforced plastics (FRP) has become the standard for lightweight structural applications. However, its production trend is shifting to the use of alternative natural materials to reduce energy costs and achieve biodegradation

now, Lorenz kunststofftechnik has developed a mass molding compound (BMC) made of jute fiber, cotton fiber or sisal fiber. According to the composition, they show performance characteristics similar to traditional FRP

depending on the application, the length of the fiber can be selected. According to this, the material can be processed by molding or injection molding

in addition, different natural reinforcement materials also open up new applications. For example, thermosetting plastics reinforced by cotton fibers are easy to spray, laminate or polish, so they can also be used in specially designed parts

this new development is based on the tested BMC 0204, which already contains two eco-friendly materials, calcium carbonate as filler and ath as flame retardant. By using new natural fibers to replace glass fibers, the energy consumption in production is reduced, thereby reducing the carbon footprint

depending on the application, you can choose the type and length of the fiber. For example, the sisal fiber reinforced mixture has a very low processing shrinkage (-0.1% ~ -0.3%), while the cotton fiber reinforced thermosetting material has a high elastic modulus of more than 8000 MPa and low wear resistance. Their density is very low, only 1.65 ~ 1.7g/cm3, which helps to reduce weight

flame retardant, moisture-proof and flexible processing

natural fiber reinforced plastics (biological composites) usually provide good heat and sound insulation properties. By changing the actual composition of BMC, these properties can be adjusted separately, thus giving normal highly flammable natural fibers excellent fire resistance

in the UL94 flammability test, the flame of a 1.5 mm thick sample can be extinguished within 10s, which is equivalent to the best fire rating of v0

It is very convenient to complete the experimental function; In addition, it is equipped with a special lengthened jaw for steel strand to ensure the fracture in the sample

in addition, the moisture absorption problem of biological composite materials, which is very common, can also be solved through the correct material composition. According to the moisture absorption test results of ISO 62, the eco-friendly BMC of cotton fiber is ≤ 0.5%, the eco-friendly BMC of jute fiber is ≤ 1.3%, and the eco-friendly BMC of sisal fiber is ≤ 1.8%

this kind of natural fiber reinforced BMC can be processed not only by molding process, but also by injection molding, which has become the largest one-time process in the history of China's railway. This means that so far, only more complex and exquisite components produced by FRP can be used, but also biological composite materials can be used

in molding, the temperature of the barrel is required to be 20 ~ 40 ℃, and the temperature of the mold itself is 140 ~ 170 ℃, which means that the material is suitable for various applications, from large automotive interior parts to small electronic components

eco friendly and recyclable

all Lorenz natural fiber reinforced thermosetting plastics can be recycled. According to the material composition, 100% of cutting and stamping waste can be reused

the energy recovery of fiber is carbon neutral, and there is no residue after combustion

since this RoHS compliant composite material does not contain halogen or any heavy metal compounds, it is generally highly eco-friendly and harmless to human body and ecosystem

in order to further improve this internal experiment and improve the quality and performance of process control, Lorenz experts have begun to study organic resin matrix materials, which will replace the currently used polyester resin. Therefore, composites made entirely of natural substances will become a reality
