Filler masterbatch – products not to be missed when mentioning Europlas brand
Filler masterbatch is considered as a typical product of European Plastic Company EuP. Within the circumstance that prices are escalated and the economy gets harder, using fillers for plastic in plastic production is an effective solution because it helps manufacturers to save a large amount of input materials, thereby reducing the product costs. In addition, the utility of filler masterbatch in manufacturing shortens the processing time, so the production capacity can achieve the optimal efficiency.
As one of the world-leading filler masterbatch manufacturer, EuP has spent many years researching customers, market demands and various types of products. To satisfy the different needs, plastic fillers of brand name EuroPlas are generated and classified into various different types, classified according to their composition. In the category based on fillers added, in addition to CaCO3 powder (producing CaCO3 filler), the manufacturer can also use Talc powder (producing Talc filler).
Filler masterbatch is made of Talc powder – an indispensable ingredient
Talc filler masterbatch is a mixture made of talc powder, base resin (PP, PE, HD, HIPS, etc.) and various additives such as dispersant additives, bonding additives, etc.
So what is Talc powder? Talc is a metamorphic mineral in solid form. The full scientific name is hydrated magnesium silicate, with the chemical formula is Mg3Si4O10(OH)2. In nature, talc is often found in a stone called steatite or soapstone (a high-talc rock), it is often combined with other minerals such as chloride and carbonate. Talc is usually blue, white, gray, brown or colorless.
In various industries ranging from plastics, cosmetics, paper, etc. talc is ground into white powder and mixed with other compounds so it is known as talcum powder. In addition, talc is also known as “soft stone”. This stone, as its name suggests, has a special softness that is often used in sculpture.
It can be said, thanks to the following 4 outstanding features, “talcum powder” or “soft stone” has very special properties that are widely applied in different fields:
- Moderate softness (Talc has the lowest hardness compared to other minerals in nature)
- Very smooth, feels like soap when touching
- Good electrical insulation, good insulation, high melting point, low thermal expansion
- Force with organic substances (capable of combining with organic substances)
- Is an inert chemical
In the plastic industry, Talc is widely used by masterbatch manufacturer to produce filler masterbatch. As a high-content ingredient in plastic fillers, talc will increase the hardness of several base resins such as polypropylene, vinyl, plastic, nylon and polyester. Moreover, it can also function as an anti-stick agent, antifreeze, lubricant, smoothing agent, etc.
The role of Talc filler masterbatch in plastic production
Talc Filler masterbatch is composed of talc powder, base resin and supportive additives. It is considered as the perfect filler for plastic that help masterbatch manufacturer improving productivity while reducing production costs. Plastic masterbatch containing talc powder can be used to replace a part of primary plastic (the input material for plastic-based products manufacturing). This is a smart solution aiming at saving raw materials while limiting the amount of crude oil – resources are gradually exhausted, in plastic production. Another great effect is that the talc filler will greatly improve the plastic properties, helping the plastic output products have higher value in the consumer market.
With outstanding advantages in the following features, talc filler masterbatch brings positive results for the plastic industry, especially the masterbatch sector. Their advanced functions include:
- Increase heat resistance for plastics
- Help plastic products enhancing its abrasion and slip resistance when contacting other products’ surfaces
- Reduce plastic shrinkage, help shaping and stabilizing the product’s sizes easily
- Improve printing features on the surface of material, limit applying surface treatment with corona.
- Increase durability for plastic
- Anti-blocking plastic, flatten the surface without using anti-block additives (enhance anti-block feature)
Talc filler masterbatch is very popular among masterbatch manufacturer because it is suitable for most traditional production processes such as bag blowing, injection molding, extrusion molding, compression molding, etc. without having to upgrade or changing the equipment or production technology. Talc fillers containing talcum powder must undergo processing stages to produce all kinds of packaging (shopping bags, food bags, garbage bags, bottles, food containers, etc.), hollow tubes, plates, electrical covers, bowls, plates, etc.
Let’s take a look at a specific example of talc filler masterbatch application in the automotive industry. Plastic fillers that are composed of talc powder, PP resin and some other additives are able to increase the hardness of PP base resin and improve impact resistance. Talc powder has the effect in increasing the bending coefficient by 20% and reducing the coefficient of thermal expansion by less than 20% so that the output products does not deform at high temperatures. This combination is suitable for creating dampers, balance parts or high-impact parts of cars.
Consideration when using talcum powder to produce filler masterbatch
Talc powder is very useful in producing filler masterbatch, but on the other hand, it will also contain immeasurable risks if we do not understand it thoroughly and use it carefully.
According to the reports, the incidence of lung cancer and respiratory-related diseases is very high among talc miners due to exposure to industrial talc powder containing silicon dioxide and asbestos which are dangerous to our health. Another problem is that talc powder is quite popular in cosmetic powder because of good moisture absorption property. That will cause a threat to babies or women when inhaling lots of talcum powder.
However, there is currently no obvious evidence that using or inhaling talcum powder will increase cancer risks. Data on the relationship between talc powder and lung cancer cases is still very small. However, talc filler masterbatch manufacturers should still be careful when using this substance in production. Employees must be trained and given clear instructions when exposed to talc and must know the exact dosage of this ingredient to minimize the harmful effects of talc.
