Introduction to Nylon
Polyamide is commonly known as nylon (Nylon), and the English name Polyamide
(referred to as PA) refers to a plastic composed of polyamide resin. This kind
of resin can be prepared by polycondensation of diamine and dibasic acid, or by
ring-opening polymerization of lactam formed after dehydration of amino acid.
Unlike PS, PE, PP, etc., PA does not gradually change with the increase of
heating temperature. Soften, but soften in a narrow temperature range close to
the melting point, the melting point is obvious, melting point: 215-225 ° C.
Flow occurs once the temperature is reached.

Nylon engineering plastics are horny, tough, bright surface, white (or light
white) or yellowish, transparent or translucent crystalline resin, which can be
painted in any color easily. As an engineering plastic, the molecular weight of
nylon is generally 15,000-30,000. Their density is slightly greater than 1,
density: 1.14-1.15g/cm3. Tensile strength: > 60.0MPa. Elongation: > 30 percent.
Bending strength: 90.0MPa. Notched impact strength: (kJ/m2) > 5.

The shrinkage rate of nylon is 1 to 2. Pay attention to the dimensional change
after moisture absorption after molding. Water absorption rate 100% can absorb
8% when relative moisture absorption is saturated. The use temperature can be
between -40～105℃. Melting point: 215-225°C. The suitable wall thickness is
2-3.5mm. Among the mechanical properties of PA, the tensile and compressive
strength changes with temperature and moisture absorption, so water is
relatively a plasticizer for PA. After adding glass fiber, its tensile and
compressive strength can be improved About 2 times, the temperature resistance
is also improved accordingly. PA itself has very high anti-wear ability, so it
can be operated without lubrication. If you want to obtain a special
lubrication effect, you can add sulfide to PA.

Nylon Molding and Post-processing
Except for transparent nylon, other nylons are crystalline plastics with high
melting points, narrow melting temperature ranges and poor thermal stability.
PA is easy to absorb moisture. During the molding process of nylon, the
viscosity drops sharply and silver threads appear on the surface of the product
mixed with air bubbles, and the mechanical strength of the product decreases.
Therefore, the material needs to be dried before processing. It can be dried at
80-110°C for 6 hours. The allowable moisture content of machining nylon 6 and
machining nylon 66 during molding is 0.1%, nylon 11 is 0.15%, nylon 610 is 0.1%
to 0.15%, and shall not exceed 0.2%. Note that PA plastics are prone to
discoloration when dried above 90°C.
