什么是 BIPB 96?
Quick answer: A strong printing-ink formulation is usually the one that keeps process stability and final print quality in balance, rather than over-optimizing only one part of the press behavior.
硫化剂 BIBP 属于过氧化物类交联剂，在硫化过程中为自由基交联，橡胶制品交联密度高，交联过程不散发刺激性气味，对环境无污染。适用的硫化方法有：模压硫化、蒸汽罐硫化、高温连续硫化。
硫化剂 BIBP
BIPB 之所以被称为无味 DCP，除了结构相似外，还有一个重要原因，那就是几乎能用 DCP 的地方都可以用 BIPB 代替，BIPB 代替 DCP 后的橡胶性能，包括硬度、断裂强度、伸长率、撕裂强度和耐油性、老化系数等基本相同，而在高温压缩变形方面，BIPB 则优于 DCP。
但 BIPB 有一个明显的缺点，即价格比 DCP 高出太多，这是限制 BIPB 广泛使用的最大因素。在欧洲，BIPB 的使用量远远高于 DCP，而且随着国内生产商和消费者环保意识的增强，目前国内对 BIPB 的需求也在不断增加。
BIPB 的另一大缺点是，用 BIPB 作为 EPDM 交联剂时，容易出现喷晶现象（注意是喷晶，不是喷霜），光照下会向上亮晶晶，而 DCP 则不会。这是由于 BIPB 的分解产物与 EPDM 的相容性差而喷出来的。如果您的产品出口到国外，特别是欧洲，您可以放心，客户会知道您使用的是好的硫化剂并欣然接受。如果要解决这种喷晶现象，主要有两种方法。
1. 在配方中添加 PEG4000。
2. 减少 BIPB 用量的同时添加部分双二五，相当于减少 BIPB 的分解产物，而不影响交联效率。
这两个方案都是成功的范例，当然也有厂家生产的三元乙丙橡胶用 BIPB 交联剂没有出现喷晶现象，也许是因为用了一些添加剂限制了喷晶，具体原因不得而知。
热塑性橡胶热塑性硫化弹性体也有使用 BIPB 作为交联剂的，但随着汽车行业对气味的要求越来越高，即使用 BIPB 后，气味不一定能达到要求，还需要进一步处理，如采用化学/物理吸附、脱挥、干燥等工艺手段来降低气味。立即联系我们！

A practical formulation view of printing and ink-processing topics
Ink performance problems are often multi-variable problems. Teams generally move faster when they screen transfer, flow, drying or curing, and substrate hold together instead of changing one raw material at a time without a clear decision frame.
- Define the real process bottleneck: poor transfer, drying problems, skinning, and color instability often need different corrective routes.
- Check viscosity inside the print process: an ink that looks fine in the container can behave very differently on the machine.
- Review substrate compatibility: paper, film, metalized surfaces, and laminates often require different balance points.
- Use post-print checks as part of selection: scratch resistance, tape adhesion, lamination behavior, and storage stability are usually as important as the fresh-print appearance.

FAQ for buyers and formulators
Why do many ink problems require more than one formulation change?
Because flow, transfer, drying, adhesion, and appearance interact, so improving one of them can sometimes worsen another if the full system is not reviewed together.
Should rheology be judged only by a single viscosity number?
Not usually. Printability also depends on transfer behavior, temperature, shear history, and how the ink behaves on the actual press.
