• Since the specific weights of 5 liters of vermiculite objects are different, kg and liters are not equivalent. For example, 1 kg of iron covers a handful, while 1 kg of cotton covers a large area. Since vermiculite is a light product, it occupies more space in volume and is less in weight. Vermiculite properties: Size: 1.4-4 mm.
