Frequently Asked Questions (FAQ)
What is the primary difference between S/B 15/85 and S/B 29/71 linear grades?
The ratio represents the styrene-to-butadiene content. S/B 15/85 offers higher elasticity, lower hardness, and better low-temperature flexibility, while S/B 29/71 provides higher tensile strength, greater hardness, and improved cohesive strength.
Are CHANGHONG grades direct equivalents to SINOPEC, JINHAI, and LUHUA grades?
Yes, the listed grades share equivalent molecular structures and core physical parameters, making them suitable cross-reference replacements across various manufacturing processes.
Which grade is most suitable for hot-melt pressure-sensitive adhesives (HMPSA)?
Linear grades with S/B 15/85 (such as CH 691, CH 606, and CH 608) are widely favored in HMPSA formulations due to their superior tack, flexibility, and compatibility with tackifying resins.
How do these polymers benefit asphalt and plastics modification?
When blended with asphalt, they substantially enhance high-temperature rutting resistance and low-temperature crack resistance. In plastics modification, they significantly improve the impact strength and toughness of rigid polymers.
