Ground Calcium Carbonate | Special

Ground Calcium Carbonate | Special

For Oral Care e Foods markets

Provale is specialized in ground carbonates oriented to Foods and Oral Care market. Currently, the company is the sole producer in Brazil to offer these carbonates with high content of CaCO3 ( > 98.00 %) and low RI ( < 0.20 %). Our products are indicated to all types of general toothpaste, and other products containing calcium as a source of enrichment.
 
Our carbonates stands out due to low abrasiveness and low economic value. When compared with other calcium sources, calcium carbonate is one of the salts with best cost, up to 50% cheaper than other calcium sources.

Calcium is an element with wealthy properties. It is the most abundant mineral in the organism corresponding to 1.5% of body weight. An adult persons needs to ingest at least 1,000 milligrams and this amount increases according to the age. One of the largest calcium sources is the calcium carbonate. Oral and Foods markets are heavily investing in this material. Get to know more about what it may offer in benefits to general health, access the website www.vivamelhorcomcalcio.com.br, a Provale initiative!

For Plastic markets

Provale ground calcium carbonates are particularly developed to meet all types of companies seeking for low abrasiveness in plastic segments, with great highlight for being an unpublished production line in Brazil.

Our carbonates are produced with low particle diameter and imported raw materials with high chemical purity. They increase resin performance, improve the resistance to impact, improve module tension (stiffness), provide bigger cycles, make the molding quicker, improve dimensional stability with less buckling, dampen the sound, provide good surface finishing and thickening.
