a single zinc aluminum metallized polypropylene edge thickened metal layer (or polyester) BT composite mesh type safety film

Base PP film for silver metallized PP capacitor film
Capacitor-used film: plated PP film's surface with a thin metal layer.
2.  metallized BOPP capacitor film
The high pure aluminum or zinc melting, in under high vacuum evaporation, precipitation to the surface base film, plastic film is formed a thin layer of metal layer after membrane surface.
3. self-healing ,  self-healing function of self-healing
Metallized film dielectric after local breakdown immediately instinctively to the electrical properties of the phenomenon of breakdown before.
4. margin,  left side margin
The need for the actual production of capacitors, metallized film on one side or both sides of the edge or middle cover form without steaming blank metallized insulation strip (strip) called the edge, its width is called the margin.
5. square resistance, The sheet resistance of square resistance
The metal layer of metal film on the unit square area of the resistance value is called the square resistance, expressed by Omega /, usually with square resistance to represent the thickness of the metal coating.
6. metallized safe film, metallic safety film metallized safety film
The metal pattern layer containing metal film fuse safety structure. According to the structural characteristics of fuse safety can be divided into grid security film, security film and T series safety film etc..
Classification: types of products

The code in the:   M said the metallization;
PP said polypropylene film;
PET said polyester film;
A metal coating for aluminum;
AZ metal coating is zinc aluminium composite;
D said the double-sided metallization;
H said edge thickened metal layer;
X said the grid security film;
T said T safety film.
2 edge type    1 classification margin products and edge character code
S -- edge on one side of the membrane, see Figure 1, figure 4, Figure 6 and figure 7;
T -- the edges at both sides of the membrane, see figure 2;
M -- margin in the middle of the film, see figure 3.
2 no margin products without edge character code, see figure 5.
3 specifications    Metallized film specifications expressed in three section of the Arabia digital, the first section number indicates the nominal thickness of metal film (m), second digital representations of metallized film width (mm), third digital representation of metallized films margin (mm), multiplication in each section numbers (x) connected.
Example: 8 x 75 x 2.5 metal film thickness of 8 μ m, width of 75mm, margin for 2.5mm
4 model      Product by product type, edge type and specification of three parts.

Though more then ten years research in the developed countries, safety film for capacitors of explosion protection has come into the large-scale production.
Its unique inner net-shaped structure is a new explosion protection mode.
