NOTE:
1. The chemical composation is calculated on dry basis removed the adhesive moisture(except the loss on ignition).
2. The round-off number rule is stipulate as 5.2 of GB1250, and the rounded digit shall be consistant with the limiting values listed in the forms.
3. Normally, NaF/AlF3 ratio is between 1.8-2.9,any special requirements should be indicated in the contract.
4. Any requirements on the loss on igniton below 2.5% should be indicated in the contract.
PROPERTIES

High
Molecular Ratio

1. 4kinds of particle size are classified as follows:
(a)The Granular:1 - 10mm
(b)The Sandy:0.074-1mm(16 - 200mesh)
(c)The Powder:≤0.25mm(60mesh)
(d)The mixture of the above (a),(b),(c)

2. Colour: Grey-white, light-yellow,light-red
The chemical compositions of the product keepstable no matter how it differs in colour and particle size.

Low
Molecular Ratio

1. Colour:white powder
2. particle size:
(a)The granulars with the size>4mm may be allowed, but their content can not be more than 5%.
(b)-300 meth≥70%.

Packing:
In plastic coating woven bags with plastic fiim and paper bags inside, 40 kgs, 50kgs or 1000kgs net each, or as the requirement of clients.
