Process: Fully tempered safety glass, dark brown privacy style, with black shading glaze edge
Front Door Upper Fixed Triangle Tempered Glass OEM 2131-5403011-21D, dark tint heat insulation safety glass with black ceramic frit edge, without frame, fit Shacman X3000 New M3000 truck cab front door quarter window, weight 1.1kg per piece.

Glass type: Fully tempered safety glass (Tempered Safety Glass), meeting the mandatory tempering standard for side windows of the vehicle. Upon impact, it shatters into non-angled particles, reducing injury to passengers and drivers.
Translucent coloration: The 21D suffix is standard for dark brown tinted heat-insulating glass, which blocks ultraviolet rays and reduces the temperature rise of the driver's cabin. The transparent models have different suffix numbers and cannot be interchanged.
Basic process
The common automotive glass is made of silicon glass, with the main component, silicon oxide, accounting for more than 70%.
1. Isotropy: The atomic arrangement of glass is random, and the atoms in the glass have statistical uniformity in space. Under ideal conditions, the physical and chemical properties (such as refractive index, hardness, elastic modulus, thermal expansion coefficient, thermal conductivity, electrical conductivity, etc.) of homogeneous glass are the same in all directions.
2. No fixed melting point: The transformation of glass from a solid state to a liquid state occurs within a certain temperature range (i.e., the softening temperature range), which is different from crystalline substances and does not have a fixed melting point. The softening temperature range is Tg to T1, where Tg is the transition temperature and T1 is the liquidus temperature. The corresponding viscosities are 10 dPa·s and 10 dPa·s respectively.


Laminated glass refers to a type of glass where a transparent and adhesive plastic film is placed between two or three layers of glass, combining the strength of the plastic with the hardness of the glass, thereby enhancing the glass's resistance to shattering. Tempered glass refers to ordinary glass that is quenched to form certain internal stresses, thereby increasing the glass's strength. When it is subjected to impact and breaks, the glass splits into small, blunt-edged fragments, minimizing the risk of injury to passengers. Regional tempered glass is a new type of tempered glass.
