Detailed Description

FKM Vulcanizator Masterbatch ● Product Description KF AF -50——50% FKM vulcanizer master batch in a copolymer FKM KF BP-33——33% FKM accelerator master batch in a copolymer FKM ● Advantage of AF-50 and BP-33 Compared with normal powder vulcanizator 1. Higher vulcanizing efficiency and faster vulcanizing rate 2. Improve FKM compound quality by better dispersion 3. Improve tensile strength 4. Reduce compression set 5. Reduce the dosage of BpAF by 5-10% ● How to adjust Recipe 　 Original Recipe Recipe with Masterbatch Gum 98 95.5 BpAF powder 1.5 - BPP powder 0.5 - AF-50 - 3 BP-33 - 1.5 Other filler N N Total phr 100+N 100+N ● Physical properties compare with powder vulcanizator 　 Low Level Vulcanizator High Level Vulcanizator Recipes A B C D E FKM Gum, 50MV 96.1 98.27 94.6 94 97.33 AF-50 2.6 　 3.6 4 　 BP-33 1.3 　 1.8 2 　 BpAF powder 　 1.3 　 　 2 BPP powder 　 0.43 　 　 0.67 N990 30 30 30 30 30 Calcium hydroxide 6 6 6 6 6 Magnesium oxide (highly active) 3 3 3 3 3 Carnauba wax 1 1 1 1 1 Total phr 140 140 140 140 140 ● The effect of AF-50 and BP-33 on MDR vulcanizator ——Faster vulcanizing rate ——Higher MH ——3.6phr AF-50(content 1.8phr pure BpAF) provides similar vulcanizing effect as 2.0phr pure BpAF · ● The effect of AF-50 and BP-33 on physical properties ——improve tensile strength ——get lower compression set 　 A B C D E Test Items\ vulcanizing Condition Slab vulcanizing,177℃×10min，Post vulcanizing,,230℃×24hours　　　　 Tensile,Mpa 14.5 13.4 14.8 15.2 14.7 Elongation,% 240 250 165 155 170 Hardness，Shore A 74 75 79 80 79 Comparession Set,%,200℃×70hours 22 24 21 21 22 Test Items\ vulcanizing Condition Slab vulcanizing,177℃×10min，Post vulcanizing,200℃×24hours　　　　 Tensile,Mpa 12.5 11.5 12.4 12.5 11.7 Elongation,% 290 290 210 200 210 Hardness，Shore A 74 73 78 79 78 Comparession Set,%,200℃×70hours 29 32 28 28 29
