Two types of cosmetics tube caps：
PE cosmetic tube caps
PE — has waxy -like, has a sense of smoothness, characterized by softness, non -toxic, low price, convenient processing, good chemical stability, and has a certain mechanical strength, cold resistance, and insulation. LDPE is easy to breathe and humid, with excellent electrical insulation performance and chemical properties. It has good softness, retractability, and impact resistance, but the mechanical strength is poor. HDPE is better than LDPE in insulation, abrasion resistance, impermented, and anti -chemical drugs. LDPE and HDPE contraction rates are larger than other plastics and are easy to deform.
PP cosmetic tube caps
PP -better liquidity, moldability, is the most commonly used heat -resistant in plastic. At normal temperature, tensile strength, high yield strength, high bending fatigue life, high chemical stability, electrical performance, electrical performance Well, but the impact strength changes with temperature changes, it is easy to shrink and deform, inadequate rigidity, affected by ultraviolet rays, aging, hard, cracking, dyeing or migration.
