         nylon is most important engineering plastics 之一, aliphatic PA, 脂肪— aromatic PA and aromatic PA. its in, aliphatic PA product types more, output/production volume large, application 广泛. flame retardant modified engineering 师们, 显然必 must for nylon this important material product “知根知底”.

         commonly used nylon can separation is large type: type is hexamethylenediamine and adipic acid polycondensation poly adipic acid hexamethylenediamine, its long separation chemical structure is: H—[HN(CH2)XNHCO(CH2)YCO]—OH. its versus for molecular weight generally is 17000-23000. according to use binary amine and binary acid carbon 原子数 different, can to different product, can through difference, its in front 一数字 is binary amine carbon 原子数, rear 一数字 is binary acid carbon 原子数. nylon 66, it is hexamethylenediamine and adipic acid polycondensation made; nylon 6 10, it is hexamethylenediamine and acid made.

        另一 type is caprolactam polycondensation or ring polymerization to, its long separation chemical structure is: H—[NH(CH2)XCO]—OH according to its mono structure carbon 原子数目, can to different product types 命名. nylon 6, it is 由含六 carbon caprolactam ring polymerization 而.

         nylon in main/primary product types is nylon 6 and nylon 66, for 主导 位, its is nylon 11, nylon 12, nylon 6 10, nylon 612, another also has nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13, new product types has nylon 6 I, nylon 9T and nylon MXD6(retardant property resin) and other.

         nylon modified product types amount more, reinforcement nylon, mono 体浇铸 nylon (MC nylon), reaction injection molding (RIM) nylon, aromatic nylon, transparent nylon, high impact resistance (super tough) nylon, electroplating nylon, conductive nylon, flame retardant nylon, nylon and other polymer blending material and alloy and other, meet/satisfy different requirements, used as metal, and other 传统材 material use product, as is various structure material.

         that 么, nylon product is how to 命名 呢? generally 讲, is use and 数字组 combined. this and 字母指出 product chemical separation, melt temperature degree, viscosity and other grade, stability property, glass fiber content and processing properties.

        第1 字母: table/sheet nylon type type

        B=PA6;A=PA66;C=PA66/6(melting point: 243℃);T=PA6/6(melting point: 298℃);KR=特殊定 made product.

        第1 数字: table/sheet viscosity and other grade

        3= flow property strong/high, low melt viscosity, main/primary used for injection molding;35= low, in and other viscosity, used for injection molding, Monofilament and film extrusion;4= in and other viscosity, used for injection molding and extrusion molding.

        第2 or 第2 and 第3 字母: table/sheet heat stabilized agent types type

        E,K= stability 化, 淡自然 color. for hot aging, outer ring and hot water has relatively good resistant property, insulation property can effect/influence;H= tool has for hot aging, outer ring and hot water has relatively good stability resistant property, used for engineering parts, electrical property can effect/influence, color;W= stability 化, high heat resistant aging property, has color and black types color, combined used for processing for electrical property can requirements relatively high parts.

        特殊 property can and additives

        HR=改良 hydrolysis resistant property;L= impact property can and stability 化, in drying lower tool has resistant impact property, flow property high, used for fast speed formed;R=PE改良 and stability 化, used for high force parts, low 噪音, low friction force;S= used for fast speed molding, fine structure, used for injection molding;U=不 belt/tape has flame retardant product; X2= belt/tape has flame retardant type product; Z= impact property can and stability 化, tool has very good low temperature resistance impact strong/high degree (未 increase product) or impact strong/high degree (reinforcement product).

         reinforcement types type

        G(附 add 数字)= glass fiber reinforcement;C(附 add 数字)= carbon glass fiber reinforcement; K(附 add 数字)= glass beads reinforcement, stability 化;M(附 add 数字)= mineral filled, stability 化, product.

         can provide glass fiber reinforcement mixed combined material

        GM(glass fiber /矿 material);GK(glass fiber / glass beads); 数字按顺序 separation table/sheet reinforcement material content: reinforcement material content (quality separation 数): 2=10%;3=15%;4=20%;5=25%;6=30%;7=35%;8=40%;10=50%. 例如: GM 53 table/sheet 示25% glass fiber and 15%矿 material, stability 化;GK 24 table/sheet 示10% glass fiber and 20% glass beads, stability 化.
